Early research suggests that CBD can alleviate some symptoms of cancer and chemotherapy, and even slow tumor growth.

Unfortunately, the CBD market is filled with thousands of products of varying quality. Many contain less CBD than advertised, while others carry pesticides or other contaminants.

That’s why we compared more than 30 pet CBD oils and treats based on their third-party lab test results, hemp quality, potency, formula, customer reviews, price, and other criteria.

Read on for our picks of the best CBD oil for cats with cancer, plus a science-based guide on using CBD for this debilitating condition.

Best CBD Oil for Cats with Cancer

CBD Terminology

  • Terpenes: aromatic plant compounds with a wide variety of beneficial properties (1).
  • Minor cannabinoids: CBN, CBG, and other beneficial cannabinoids found in smaller amounts than CBD. For hemp, THC also counts as a minor cannabinoid.
  • Hemp: non-intoxicating cannabis variety with high CBD and low THC levels (less than 0.3%).
  • Full-spectrum: whole-plant hemp extract containing multiple cannabinoids, terpenes, and flavonoids. This form of CBD is about 4 times more potent than pure CBD (2).
  • Broad-spectrum: whole-plant hemp extract similar to full-spectrum CBD, but with THC removed (may contain trace amounts).
  • CBD isolate: pure CBD with all other hemp compounds removed.

Receptra Naturals Pet Tincture (Best Overall)

Pros:

  • Two potencies
  • Full-spectrum CBD
  • Great price
  • Extensive third-party testing
  • Organic Colorado hemp source
  • Free shipping

Cons:

  • No flavored options

Use code RECEPTRACBD10 for 10% Off

Our top pick is Receptra Naturals, a company recognized for its high quality. Its pet CBD oil is an excellent choice for cats with cancer.

This tincture is made with full-spectrum CBD, which means it contains multiple beneficial cannabinoids and terpenes. Full-spectrum products are more effective than those containing a pure form of CBD (isolate).

It’s available in two strengths (16 mg/ml and 25 mg/ml) although we recommend the stronger version since cancer is a serious condition. This tincture provides a total of 480-750 mg of CBD in a 30 ml bottle.

Receptra Naturals grows its organic hemp on a small family farm in Colorado. Its products are comprehensively tested by a third-party lab.

Receptra’s full-spectrum pet CBD oil costs $0.09 per mg of CBD. As far as pet CBD tinctures go, this price is considered below-average.

Lazarus Naturals CBD Pet Tincture (Best Value)

Pros:

  • Exceptionally low price
  • Full-spectrum CBD and isolate versions
  • Extensive third-party testing
  • Multiple bottle sizes
  • Organic, high-quality Oregon hemp source

Cons:

  • Only one potency option

If you’re looking to get the best value, we recommend Lazarus Naturals.

This company is known for offering high-quality products at unbeatable prices. Its pet CBD oil costs only $0.03 per mg of CBD, which is far below the price of most competitor brands.

These third-party tested tinctures are made with full-spectrum CBD. You can choose the classic or salmon flavor.

Lazarus Naturals’ pet CBD tincture contains 300-2400 mg of CBD and has a potency of 20 mg/ml, which is fairly high for cats. It comes in multiple bottle sizes (30 ml, 60 ml, 120 ml) and has a salmon flavor.

Better yet, the CBD is derived from organic hemp grown in Oregon which comes from Lazarus Naturals’ own farm. An employee-owned company, Lazarus Naturals is known for its excellent quality, transparency, and commitment to low prices.

NuLeaf Naturals Full Spectrum Pet CBD Oil (Strongest)

Nuleaf’s full-spectrum pet CBD oil has a per-mg price of $0.08–0.10, which is cheaper than average for pet tinctures.

Cannimal Eva’s Blend (Best Formula)

Pros:

  • Anti-cancer formula
  • Whole-plant hemp extract
  • Third-party tested
  • Organic Colorado hemp source
  • Free shipping

Cons:

  • Lacking third-party tests for contaminants

The Eva’s blend tincture from Cannimal is one of the only pet CBD products formulated specifically for cancer. Although it was inspired by a dog suffering from cancer, there’s no reason it can’t be used for cats.

This CBD oil contains dried turkey tail mushroom (Trametes versicolor), which has been used in cancer treatment in Japan for decades. Research studies show that it can improve immune system function in cancer sufferers and may potentially suppress tumor growth (3, 4).

Cannimal’s 50 ml tincture is available in four strengths containing 150, 250, 1000, or 2000 mg of CBD derived from organic, Colorado-grown hemp. It’s made with broad-spectrum CBD, a type of hemp extract which contains multiple beneficial cannabinoids and terpenes but no THC.

Cannimal’s tincture comes with a gel pump to make it easier to administer to pets and a Miron glass bottle, which extends CBD’s shelf-life by protecting against sunlight.

It costs $0.08–0.27 per mg of CBD. That’s a fairly reasonable price for such a unique, cancer-focused product.

Holistapet CBD Cat Treats (Best Treats)

Pros:

  • Full-spectrum CBD
  • Affordable price ($0.17 per mg)
  • Cat-friendly flavor
  • Third-party tested
  • Free shipping
  • Organic Colorado hemp source

Cons:

  • No third-party tests for contaminants

Although CBD oil tinctures are the ideal form of CBD for cancer, infused treats can be an effective addition. Our top pick for this category is Holistapet, a company dedicated to CBD products for pets.

The company’s CBD cat treats contain 2 mg of full-spectrum CBD each. By comparison, the vast majority of cat treats are made with CBD isolate, a pure form of CBD. Full-spectrum hemp extract is the ideal form of CBD for cancer because it offers stronger benefits than CBD isolate.

These edible treats have a pleasant salmon flavor and contain only natural ingredients. There are 75 pieces per bag, for a total of 150 mg of CBD, sourced from organic Colorado hemp.

Holistapet’s CBD cat treats cost $0.17 per mg of CBD. This price is similarly to most CBD-infused pet treats.

Buying Guide for CBD Oil Products for Cat Cancer

What is CBD?

Cannabidiol (CBD) is one of the more than 100 cannabinoids present in cannabis. Unlike tetrahydrocannabinol (THC), the best-known cannabinoid, CBD doesn’t make you high.

CBD offers a wide variety of health benefits for both humans and pets, such as reducing anxiety, improving sleep, and alleviating pain and inflammation.

There’s also some evidence that it can help with cancer and other debilitating conditions. CBD is typically sourced from hemp, a legal type of cannabis with low (<0.3%) THC levels.

What is CBD Oil?

CBD oil is the most popular type of CBD product. It consists of two major ingredients:

  1. CBD extract: cannabinoid-rich oil extracted from the flowers and other above-ground parts of hemp. Cannabidiol is the main active compound in this extract but it can also contain other cannabinoids and many other beneficial compounds such as terpenes, flavonoids, and fatty acids.
  2. Carrier oil: a plant-based oil that helps the body absorb CBD and makes it easier to dose. Coconut-derived MCT oil is the most common carrier oil.

CBD oil can also contain flavoring and other active ingredients.

Keep in mind that CBD oil is not the same thing as hemp seed oil, which is cold-pressed from hemp seeds, not the plant. This oil does not contain any CBD or other cannabinoids.

Benefits of CBD for Cat Cancer

CBD has many beneficial properties that can improve the lives of cats suffering from cancer. There’s evidence that:

  • CBD can reduce anxiety and promote relaxation
  • CBD can reduce pain associated with cancer and chemotherapy
  • CBD can alleviate nausea and vomiting caused by cancer and chemotherapy
  • CBD can also help with allergic reactions that may be caused by some chemotherapy drugs
  • CBD may even be able to directly slow cancer tumor growth

Let’s take a closer look at specific research studies highlighting these effects.

CBD and Cancer: The Research Evidence

There’s a growing volume of research demonstrating the benefits of CBD and other cannabinoids for cancer. For starters, there’s evidence that CBD has direct anti-cancer effects that can slow tumor growth: (5)

  • Several petri dish studies found that CBD had anticancer effects against leukemia cells (6, 7)
  • A 2006 study found that CBD suppressed breast cancer growth better than four other cannabinoids, while a 2018 study found that it promoted the death of breast cancer cells (8, 9)
  • A 2012 study reported that CBD reduced tumors and had other beneficial effects in mice with colon cancer (10)
  • According to a 2015 review paper, animal studies suggest that CBD may slow the progression of breast, lung, prostate, colon, and other types of cancer (11 )

Furthermore, there’s evidence that CBD can alleviate symptoms caused by cancer and chemotherapy, such as pain, nausea, vomiting, and allergic reactions:

  • One 2013 study reported that CBD reduced pain caused by Paclitaxel, a chemotherapy drug (12 )
  • A 2010 clinical study found that the combination of THC and CBD relieved pain in cancer sufferers better than THC by itself (13)
  • A 2002 study found that CBD alleviate nausea in rats, leading the researchers to conclude that it “may have therapeutic value in the treatment of chemotherapy-induced nausea” (14)
  • A 2019 study found that CBD reduced inflammation in mice with allergic asthma, suggesting that it may help ease allergic creations to chemotherapy drugs (15)

Although more research specifically looking at feline cancer is needed, the current evidence suggests that CBD can improve the quality of life of animals suffering from cancer and potentially even slow cancer tumor growth.

How Can CBD Oil Help Cats With Cancer

CBD produces most of its anti-cancer effects by interacting with the endocannabinoid system (ECS). This system is about 600 million years old and present in humans, cats, dogs, and many other animals (16).

The ECS regulates major bodily processes such as pain, immunity, sleep, mood, digestion, cognition, and appetite to maintain an internal state of balance called hemostasis. It consists of cannabinoid receptors, endocannabinoids (cannabinoids made by the body), and enzymes that help break and build these compounds.

Although the ECS in cats and other animals has not been studied extensively, we do know that it functions similar to how it works in humans.

Research suggests that the endocannabinoid system can help with cancer in many ways:

  • Cannabinoid receptors affect cell survival and other processes that hold the key to suppressing cancer (17)
  • The endocannabinoid anandamide has been shown to promote the destruction of cancer cells, reduce the migration of cancer cells, and prevent the formation of new blood vessels by tumors (18, 19)
  • Cannabinoid receptors can also stimulate the immune response against cancer (17 )
  • The endocannabinoid system’s regulatory effects mean that it can help with pain, inflammation, nausea, and other symptoms of cancer and cancer treatment

CBD helps support these and other functions of the endocannabinoid system by elevating the levels of endocannabinoids (20).

In addition, CBD has been demonstrated to help with symptoms of cancer and chemotherapy in other ways, such as:

  • Interacting with other parts of the body that regulate pain and inflammation, such as glycine receptors and adenosine (21, 22)
  • Interacting with serotonin receptors, which may explain CBD’s anti-nausea and anti-vomiting effects (23)

The bottom line: cats have an endocannabinoid system just like humans, and it can respond to CBD and produce beneficial effects.

Is CBD Oil Safe for Cats?

CBD is considered safe for cats and other animals. Although one study did mention increased licking and head shaking in some cats who were given CBD oil, there were no serious side effects reported (24).

Aside from that, numerous studies of CBD in dogs and mice have also found that it’s a generally safe substance with few side effects.

Additionally, CBD has been shown to have few and minor side effects in people, such as tiredness, dry mouth, and diarrhea, so it’s possible that similar effects may occur in cats and other animals (25).

The World Health Organization (WHO) concluded in its 2018 report that “CBD is generally well tolerated with a good safety profile” (26).

Nonetheless, we recommend consulting your vet before giving your cat CBD. If available, a qualified vet is always the best source of knowledge.

Tips to Maximize The Benefits of CBD Oil in Cats

If you’re interested in trying out CBD oil to help your cat’s cancer, here are some key tips to keep in mind:

  • Opt for full-spectrum CBD products over pure CBD (isolate). Full-spectrum products offer greater benefits thanks to the entourage effect (1).
  • You may need to find pet CBD products with a higher potency than normal for optimal relief. Look for products with a potency of 4 mg/ml or higher.
  • Only buy from companies that provide third-party lab test results confirming the potency and safety of their CBD products.
  • Try to apply CBD oil directly under the tongue or at least the mouth rather than adding it to your cat’s food, as this will result in greater effects due to greater absorption.
  • CBD oil is far more effective than edible cat treats. Edible CBD products should only be used in addition to CBD oil.

CBD Oil Dosage for Feline Cancer

Just like with people, there’s no ideal dosage of CBD that will work for all cats with cancer. There are simply too many factors, such as the severity of the symptoms, the benefits you’re looking to achieve, the weight of your cat, and the type of product you’re using.

The best-case scenario is to talk with a veterinarian knowledgeable about CBD or cannabis to suggest the right dosage for your cat.

If that’s not possible, start with the dose recommended by your product. From there, you can assess how your cat responds and gradually increase the dosage over several days and weeks until you see the desired effects. Be patient and consistent as the effects of CBD can be subtle and build up over time.

As a general guideline, doses of 0.25–0.5 mg of CBD per lb of body weight are sufficient for cats. However, since cancer is a serious condition, you may need to use higher dosages.

How To Give Your Cat CBD Oil

Although CBD oil can be simply added to your cat’s food, we highly recommend using the sublingual (under-the-tongue) method, or at the very least applying it directly to the mouth.

While your cat is unlikely to cooperate, this method of administration has greater benefits because the CBD can be absorbed directly into the bloodstream through tiny blood vessels in the mouth.

By comparison, oral products have notoriously low absorption because they have to pass through the digestive system.

CBD Oil vs. Edible Treats for Feline Cancer

Aside from tinctures, cat CBD products also come in other forms such as edible treats. Although such products are also beneficial, they are not nearly as effective as standard CBD oil due to low bioavailability (absorption).

Simply put, when CBD is ingested, much of it is lost in the digestive tract before reaching systemic circulation. In fact, research studies estimate that only about 6–19% of CBD that’s taken in an oral form reaches the blood (27, 28).

Due to this, it’s best to only use cat treats as an addition to CBD oil rather than a replacement.

CBD Oil vs. Standard Cat Cancer Treatments

Feline cancer is treated in a similar way to cancer in humans. Surgery is the most common option for cancer-related lumps or bumps and is the most likely to cure the disease.

Meanwhile, more aggressive types of cancer are typically treated with chemotherapy or radiotherapy. This includes lymphoma, the most common type of cancer in cats.

Unfortunately, the survival rate for cats undergoing these treatments is lower than with surgery, and treatment is focused primarily on improving quality of life rather than a cure. Additionally, the costs of all of these treatments are not cheap, and can easily cost upwards of $5000.

In that sense, CBD can be a cheaper alternative that can also be used alongside standard medical therapy. Still, we want to stress that while CBD is promising, there isn’t yet enough evidence to call it a reliable treatment for cat cancer.

Can I Give My Cat “Human” CBD Oil?

You absolutely can use regular CBD oil for your pet. After all, the two main ingredients, CBD extract and carrier oil, are the same in both pet and human products.

Having said that, regular “human” CBD oil is much more potent than tinctures designed for cats. Due to this, we recommend paying close attention to the potency of your oil and using small doses.

Can Cats with Cancer Use CBD Oil?

Cancer is one of the most feared health conditions today, and although it is not as common in cats as it is with dogs, it still affects many felines. Some of the symptoms of cancer in cats include persistent sores, lumps that change in size or shape, lameness, unexplained bleeding, and loss of appetite. (8 )

Despite having no cure, there are many medications available that can alleviate the clinical signs of cancer. However, these pharmaceutical drugs also bring with them adverse reactions and harmful side effects that can only worsen the condition of a pet.

One particularly promising solution comes in the form of cannabidiol (CBD), which is the non-psychoactive component of cannabis and the main compound in the hemp plant.

There is a growing number of owners that are beginning to look towards CBD-based cannabis products to ease pain and other conditions in their pets. (9 ) Although there is no precise data suggesting that CBD can cure cancer, there are studies that point towards its therapeutic potential and compatibility in small animals. (10 )

One study in 2018, for instance, shows encouraging results on the effects of hemp-based cannabidiol and terpenes on dogs suffering from osteoarthritis. The majority of the dogs that consumed CBD oil during the trial experienced significantly less pain and better mobility overall. (11 )

The same study also shows that there were no side effects reported and that the dogs can tolerate a dosage of 2 mg per kilogram bodyweight of CBD oil twice each day. These findings may be an indication that the hemp-based nutraceutical is not dangerous for animals. (12 )

A study on the endocannabinoid system (ECS) reveals that humans and animals, with the exception of some insects and protozoans, share this same system in their bodies (13 ) . The ECS is responsible for regulating the functions of the brain, endocrine, and immune tissues, while it also contains cannabinoid receptors. (14 )

Since animals and human beings also possess the same receptors, this means that cats can be naturally receptive to the cannabinoids present in CBD. This research on the ECS may be proof as to why the dogs in the study mentioned earlier did not experience any adverse effects upon consuming CBD oil.

CBD for Cats with Cancer

Three forms of CBD products for cats are available at this time. These include:

CBD Oils (Tinctures)

Oils are the most popular method in administering full-spectrum cannabidiol in cats. When people mention CBD oil for cats, this typically means using tinctures to help ease symptoms.

Cat CBD oil is given by way of a dropper, which is easily applied in the mouth. There are various flavors available for CBD tinctures that pet owners can choose from today.

CBD Capsules

CBD in the form of capsules is an ideal alternative for use in cats as they are provided in pre-measured portions. Each pill can be administered once or twice a day, depending on the recommendation of a veterinarian.

A capsule may contain 5 to 20 mg of CBD, so it is essential to consult a doctor before application. The pills can also be masked in pet food to make administration easier.

CBD Cat Treats

CBD pet treats for cats are also another way to administer CBD to a feline friend conveniently. Cats enjoy consuming treats that are made for them, and this product makes the application process straightforward.

Keep in mind, however, that the dosage in CBD treats may not be as accurate as with oils and capsules. Again, cat owners should talk to a veterinarian to know the proper dosage they should give to their pets.

Can CBD Oil Treat Cancer in Cats?

There are several clinical studies that were carried out, suggesting that CBD can fight the spread and growth of cancerous tumors in cats.

CBD Might Help Eliminate Cancer Cells

In 2011, researchers carried out an examination of how CBD would interact with breast cancer cells. Although the study was done in vitro, which means that it involved using either a sample dish or test tube instead of a live organism, the results were quite impressive.

In the study, the scientists learned that CBD could help induce programmed death on the cancer cells without causing much damage to the healthy cells. (15 ) How CBD was able to do this is relatively unclear, but the compound was able to help destroy damaged tissues, and cause apoptosis or programmed cell death.

Since cancer is primarily characterized by the abnormal growth of cells, the results of this study may be a hint that CBD can contribute in regulating cell growth.

CBD Can Help Stop Tumor Growth

The Breast Cancer Research and Treatment journal published a similar study in the same year regarding CBD and how it affects cancerous cells in the breast.

The study, although carried out on mice, found that CBD can help slow down the growth of breast cancer cells in these rodents. Additionally, researchers also discovered that it could reduce metastasis or the development of secondary malignant growths. (16 )

Another study in 2003 revealed how there are cannabinoid receptors present in healthy and cancerous skin cells of mice. The researchers targeted these receptors and found that by activating the ECS with cannabinoids, the compounds contributed to cell death while helping slow down skin cancer growth. (17 )

There are also several studies regarding CBD and its ability to inhibit angiogenesis. Angiogenesis is the process that allows cancerous tumors to continue growing by way of developing new blood vessels. (18 )

Side Effects That CBD May Help Alleviate

CBD oil is not an approved treatment for cancer in cats. However, it is capable of providing relief to many of the side effects that come with cancer treatment.

Three prevalent options for treating cancer in cats are done via surgery, chemotherapy, or radiation therapy. Although it is impressive to have these choices to manage cancer cells in felines, these treatments have a lot of undesirable effects, especially long-term.

Below are the side effects that CBD may help alleviate in cat cancer treatment:

Nausea and Vomiting

Nausea is a common outcome for cats that undergo chemotherapy and radiotherapy to control the growth of cancer in their bodies. During such treatment, cells that line the intestines and stomach of a cat can be affected, leading to nausea and vomiting. (19 )

There is encouraging evidence that demonstrates how the manipulation of the ECS in animals can regulate this digestive problem.

A study in 2011 shows that a wide variety of animals have the capacity to use the anti-emetic effect of cannabinoids in their bodies. Additional evidence also reveals that cannabinoids may be useful in treating nausea caused by chemotherapy. (20 )

Since CBD is a phytocannabinoid, it is theoretically possible to use it to engage the ECS of cats after they receive chemotherapy to ease their gastrointestinal issues.

Chronic Pain

Tumors that are present in any part of a cat’s body can cause mild to severe pain. Therapies such as radiotherapy, chemotherapy, and surgery can also lead to pain management issues.

Tramadol is a common analgesic given to cats that are suffering from cancer pain. However, its effectiveness is questionable in treating acute or traumatic pain, and its non-opioid mechanism may not work on felines. (21 ) The latest data suggests doses of 2 mg/kg are effective for tramadol.

In 2018, a study on dogs that had osteoarthritis were given CBD oil products to see the safety and analgesic effect it had on canines. The final assessment showed that the dogs had significantly less pain after the CBD treatment and became more active. (22 )

This clinical trial also reported that there were no ill side effects observed despite being given 2 mg per kilo of body weight every twelve hours for four weeks. (23 )

Inflammation

Squamous cell carcinoma in felines can start as a small patch of sore skin and oral tumors, which, if not healed, could be a sign of cancerous cells present in the body. Inflammation of the skin is one of the most common symptoms of squamous cell carcinoma in cats.

Research in 2000 reveals that cannabinoids, particularly with CBD from the cannabis plant, have strong anti-inflammatory properties. This same study investigates cannabinoid efficacy on mice that had collagen-induced arthritis and showed that it was able to improve the conditions on these rodents. (24 )

A follow-up experiment in 2004 using a novel synthetic cannabinoid acid on mice with arthritis generated the same results. The cannabinoid was found to have suppressive effects on cell immune responses while also producing pro-inflammatory mediators, a hint to its usefulness as a novel, anti-inflammatory product. (25 )

Causes of Cancer in Cats

There are several reasons why cancer can show up in the mammalian body of a cat.

Aging

The process of getting older is one of the primary causes of cancer in many cats. There are several reasons as to why aging can cause a higher rate of cancer growth in the body.

One theory is that the mutations on these cells accumulate over the years, which raises the likelihood of cancerous cell division to happen. (26 ) Degeneration of the mammalian body is also another suspect.

For instance, chronic inflammation experienced by cats over the years can damage DNA and weaken the immune system, leading to slow identification and elimination of harmful cells.

Fibrosarcoma

Fibrosarcoma is a common soft tissue cancer in cats that is caused by a combination of genetic and environmental factors. Although no specific cause can be identified, most cats that have fibrosarcoma developed tumors at a prior injection site on their bodies. (27 )

Intact Reproductive Organs

Cats that are not spayed or neutered are at risk of developing cancer in their bodies. The spaying of female cats eliminates the possibility of breast and ovarian cancer, while neutering male ones reduce the incidence of prostate cancer. (28 )

Apart from reducing the risk of cancer development, cats can also live longer and healthier lives when they are spayed and neutered. (29 )

Carcinogens

These chemicals are believed to cause mutations in the genes that eventually become cancerous cells in the body. Cats can be exposed to the same carcinogens as that of humans, which include those coming from tobacco smoke, asbestos, x-ray radiation, and benzene. (30 )

Possible Side Effects of CBD in Cats

Prior to administering CBD to a cat, pet owners should understand its potential side effects so that they are fully aware and prepared for what could happen. Although studies did show that CBD did not cause any adverse reactions during the trials, every cat can have a different response, and there is always the risk of harm.

The probability of these side effects can be higher with the improper use of CBD. Cat owners that notice a negative change in their pet’s attitude may consult a veterinarian to reduce their CBD dosage.

A potential side effect of CBD hemp oil consumption is drowsiness. (31 ) In many cases, cats tend to portray sleepy behavior, which makes this reaction relatively difficult to notice at first.

Nausea, anxiety, changes in appetite, vomiting, weight loss, and disorientation are also other possible side effects of CBD use in cats. Although these reactions are rare, owners should cease applying CBD and contact a veterinarian immediately when they notice these signs.

Conclusion

Cancer in cats may not be as common as they are with dogs, but the symptoms felines experience can lower their quality of life significantly. Some of these signs include persistent sores, lumps that change in shape or size, unexplained bleeding, loss of appetite, and lameness.

There are many medications that pet owners can buy to help alleviate these symptoms. However, pharmaceutical drugs are known to cause adverse reactions that can only worsen the condition of a cat suffering from cancer.

Cannabidiol (CBD) is a promising solution that offers many potential health benefits in easing the symptoms of cancer in felines. Many pet owners are beginning to look towards high-quality CBD-based products with less tetrahydrocannabinol (THC) to help reduce the pain, inflammation, and other conditions their pets are experiencing.

Preliminary research studies on pet CBD show impressive results with the phytocannabinoid being able to help inhibit and even eliminate cancerous cell growth in the body. CBD may also provide relief to several clinical signs related to feline cancer.

However, the lack of in-depth studies on CBD use in animals leaves many questions unanswered, including the possible side effects of its use. Pet owners that notice any adverse reaction in using CBD should cease its application immediately and consult a veterinarian as soon as possible.
