How to Choose the Best CBD Oil for Cats with Cancer

Below we’ll walk you through the various steps in determining which CBD oils for cats with cancer will work best for you and your feline friend.

Quality of CBD Oil

As with any product you purchase for your cat, choosing the best CBD oil is essential to getting results. Look for an organic, third-party tested CBD oil that has been extracted using CO2 rather than chemical solvents.

The ingredients should include only 100% pure, unrefined coconut oil or hemp seed oil, and organic peppermint extract for flavoring.

Flavor Options

CBD oils come in different flavors, which can make them easier to ingest. Your cat may not like the taste of CBD oil on its own, so flavored CBD oils are a great option. Flavors vary widely based on the company and their manufacturing process, but common flavors include peppermint, vanilla, and grape.

Size of Dose

Standard CBD oil dosages for cats range from 1-4.5 mg per pound (2.2 mg/kg). Some companies offer much higher dosage options as well as smaller dosage options for cats that need a lighter dose.

Method of Consumption

There are many ways to give CBD oil to cats. Topical CBD oils (oils that are administered by rubbing them on the skin) tend to be favored for their ease of use, discretion, and quick absorption into the muscles and joints where they’re needed.

CBD oil can also be given orally through drops or chews. CBD oil drops are quick and easy to use, but cats can be inconsistent with their doses when using this method.

How much does CBD oil cost?

Most pet owners find that CBD oil is very affordable when they buy it in bulk. However, the cost of CBD oil may increase if you need to cover a large area when applied topically or purchase an organic product.

If your cat needs to take 5 mg of CBD oil every day, then it’s best to give him or her daily doses of a product that contains at least 50mg in each serving.

In this case, the price of CBD oil per day would be less than a dollar. However, you may also want to consider buying a larger container of CBD oil so that you have a steady supply on hand for your cat.

Does CBD oil shrink tumors in cats?

There is a growing body of research that shows how CBD oil can fortify and enhance the effects of traditional cancer treatments. Because CBD oil doesn’t contain any psychoactive compounds, pet owners can safely give it to their cats even during chemotherapy.

Do I need a medical marijuana card to buy CBD oil for my cat?

NO. You do not need a medical marijuana card to buy and use CBD oil for your pet. Some pet owners obtain CBD oil from dispensaries under their own medical marijuana card, but you can also buy it online or in most health food stores.

Is CBD Oil Legal in all 50 states?

YES. CBD oil has been completely legalized in all 50 states. There are no legal restrictions on the ownership, transport, or use of CBD oil. Pet owners aren’t required to obtain a medical marijuana card to purchase and use CBD oil for their cats.

What are the benefits of giving CBD oil to my cat with cancer?

CBD oil can help your cat with cancer in a number of different ways. It has anti-inflammatory properties, so it can reduce pain and swelling throughout the body.

It also has antioxidant properties that fight free radicals and prevent oxidative damage to cells throughout the body. CBD oil can also stimulate appetite in cats with cancer who may not feel like eating.

Final Thoughts on Best CBD Oils for Cats with Cancer

As you can see, there are a number of benefits to giving your cat CBD oil if he or she has cancer. CBD oil is a safe and natural way to reduce pain, swelling, and nausea, and it can also help stimulate appetite.

Types of Cancer in Cats

Just like humans, cats can get cancer at any time in their lives. Many types of cancer threaten the health and well-being of cats. Although there are many more than four types of feline cancer, we will go through some of the most common cancer types in cats, including leukemia, lymphoma, feline squamous cell carcinoma, and mammary cancer.

1. Leukemia And Lymphoma

Leukemia and lymphoma in pets can stem from the feline leukemia virus (FeLV). It can spread from one feline to another, particularly through mutual grooming and sharing of food bowls. That is why, infected cats should not be in contact with healthy pets.

Both leukemia and lymphoma are life-threatening blood cancers, and they can typically be diagnosed with a physical exam, blood test and/or diagnostic imaging.

2. Feline Squamous Cell Carcinoma

Squamous cell carcinoma is skin cancer. Cancerous growths spread in the squamous epithelium, which is the outermost layer of the feline’s epidermis. They can move from one layer of the skin to another, which means it can metastasize (spread throughout the body) over time, especially if it goes unnoticed and untreated.

3. Mammary cancer

Both male and female cats can develop mammary cancer as they both have mammary glands. Sadly, the vast majority of feline mammary cancers are malignant so it is especially important to find and treat them early.

Potential Benefits of CBD Oil for Cats with Cancer

It may offer a whole host of benefits to your feline companion. However, it is crucial to understand that many of these benefits are anecdotal and clinical trials are extremely limited in the world of veterinary medicine.

It has been proposed that CBD oil:

  • Relieves inflammation.
  • Eliminates digestive problems.
  • Relieves nausea.
  • Reduces pain and aches.
  • Helps overcome stress.
  • Reduces seizure frequency.
  • Helps with epilepsy symptoms.
  • Fights disease-causing viruses.
  • Blocks the growth of cancer cells.

Be aware that CBD is not yet established as a treatment for cancer and should not be relied upon for this function. Certainly, it is thought it may help to ease the discomfort and nausea associated with some cancers and there is the potential for some cancer-fighting properties.

Possible Side Effects of CBD in Cats

Before introducing a cat to this product, pet parents need to understand its possible side effects so that they are prepared for potential consequences. While research has shown that CBD appears to be relatively well tolerated within the feline population each cat can have a different reaction and it is especially tricky to predict the reaction of chronically and seriously unwell patients. [6] ​

The likelihood of any side effects may be higher if CBD is used incorrectly. Pet parents who notice negative changes in their pet’s behavior should always consult with their veterinarian.

One possible side effect of consuming CBD hemp product is sleepiness. In general, unwell cats tend to display sleepy behavior, sometimes making this reaction difficult to detect at first.

Aggression, anxiety, nausea, vomiting, weight loss, and changes in appetite are also other potential side effects. Although these symptoms are quite rare, pet parents should stop giving CBD to their pets and immediately schedule a visit with their vet.

How does CBD oil help with cancer in cats?

Research is currently limited both in the human and veterinary world but it is hoped that CBS has many benefits to offer. It is being looked in to as a standalone cancer treatment as well as a medicine to be used adjunctively in those patients suffering from side effects such as nausea and appetite loss.

1. May Help Eliminate Malignant Cells

In 2011, scientists studied how CBD would interact with malignant mammary cells. They learned that CBD can help eliminate malignant cells without causing much harm to healthy cells. Since cancer leads to abnormal cell growth, the results of this study may indicate that CBD can induce programmed death on the malignant cells and regulate cell growth.

2. May Help Stop Tumor Growth

In another study, conducted on mice, it was deduced that CBD may help slow down the growth of malignant mammary cells in these rodents. Also, the scientists found that it can reduce the development of secondary malignancies.

In 2003, a further showed that cannabinoid receptors are present in healthy and malignant skin cells of mice. The scientists found that by activating ECS ​​with CBD, the compounds promoted cell death, helping to slow down the spread of skin cancer. [1] ​ [8] ​

Is CBD oil good for cats with cancer?

These products are not a treatment for feline cancer. However, it may alleviate many of the side effects associated with cancer treatments.

Three common treatment options for feline cancer are surgery, chemotherapy, or radiation therapy. While it is impressive to have these options to fight cancer in cats, these treatments may have some negative effects.

Below you can find the undesirable effects that CBD can help provide relief for when treating feline cancer:

Nausea and Vomiting

Nausea is a common symptom in cats that receive chemotherapy and radiation therapy to control the growth and spread of malignant cells. During this treatment, the cells lining the stomach may be affected, resulting in nausea and vomiting.

There is encouraging evidence showing how CBD can eliminate these gastrointestinal issues.

In 2011, research showed that a lot of animals can benefit from the anti-emetic effect of CBD. Additional evidence also suggests that it may be helpful in treating chemotherapy-induced nausea.

Chronic pain

Malignant tumors in any part of a feline’s body can cause pain. Similarly, those who undergo surgery can experience pain, especially in the period just after the procedure.

As an example, Tramadol is a common pain reliever given to felines with cancer. However, its effectiveness in treating pain is doubtful, and its non-opioid mechanism may not work on cats.

In 2018, canines with osteoarthritis were given CBD to see the pain-relieving effects it had on dogs. The final evaluation showed the dogs had much less pain after the CBD treatment and became more playful and active. This study also showed that there were no negative side effects observed.


In 2000, research showed that these products potentially have strong anti-inflammatory properties. The same study shows the effectiveness of CBD on mice suffering from collagen-induced arthritis and reveals that it may improve the overall condition of these animals. CBD’s products are proved to produce pro-inflammatory mediators, indicating their usefulness as a new anti-inflammatory product. [2] ​

Can CBD Oil Treat Cancer in Cats?

There is no solid evidence, yet, as yet, that we can use CBD as a cancer treatment.

We know that cancer often significantly impairs the quality of cats’ life. Symptoms such as lameness, bleeding, aches, and lowered appetite are common in felines with cancer. CBD may help to ease digestive issues, reduce aches, relieve nausea and more. However, owners should also be aware of the more traditional tried and tested medicines available, such as potent anti-emetics and corticosteroids.

When it comes to cancer treatment, the mainstay remains chemotherapy, radiotherapy and surgery where it is an option.

How quickly does CBD oil work in cats with cancer?

It takes approximately 30 minutes to achieve the full effect and lasts for about 5 hours, depending on the cat’s breed, overall health, activity level, and their metabolism. [4] ​

Is CBD legal for cats?

It is not only safe for pets, but it is also legal. CBD for felines is derived from hemp, which means the oils are extracted from hemp plants, not marijuana. Hemp plants naturally contain less than 0.3% THC, making them safe for felines.

There is a misconception that these products should have absolutely no THC. Your fluffy friend can consume CBD, which includes a THC concentration of no more than 0.3%, so your cat will not get high. [5] ​

Keep a close eye on the amount of THC in CBD tincture before introducing your cat to a new product. Make sure the bottle has a label that says ‘CBD oil is suitable for cats’.
