How Does CBD Oil Help Treat Cats With Cancer?

CBD oil helps treat cats with cancer through its anti-cancer properties and ability to reduce pain, nausea, and inflammation effectively. Plus, CBD boosts the effects of mainstream anti-cancer treatments. 

“CBD can modulate the tumor microenvironment,” affecting its growth and spread, reports a study, “Cannabidiol (CBD) in Cancer Management,” published in Cancers in 2022. 

According to the Animal Cancer Foundation, CBD shows anti-tumor properties against several types of cancer in pets, including lymphoma, mammary carcinoma, osteosarcoma, glioma, and transitional cell carcinoma. 

Despite its direct effect on specific cancer types, CBD is not a definitive cure. Used correctly, it is a supportive treatment that also helps with some cancer symptoms, primarily pain, nausea, and inflammation. 

CBD oil for cats is safe to combine with traditional cancer treatments, such as chemotherapy or radiation. Used together, CBD boosts their efficacy and minimizes their side effects. 

What Is the Recommended Dosage of CBD Oil for Cats With Cancer?

The recommended dosage of CBD oil for cats with cancer is between 1 and 5 mg of CBD per 10 pounds (4.5 kilograms) of body weight. 

The exact CBD dose depends on the cat’s needs and the severity of the cancer and symptoms. Always start with a lower CBD dose and gradually increase the amount. 

For example, a 5-pound cat needs between 0.5 and 2.5 mg of CBD oil daily. You can start with a 0.5 mg dose and work your way up to 2.5 mg or less, depending on the severity of the symptoms. 

Slow CBD introduction gives the cat’s body time to adjust, reducing the risk of CBD side effects. Do not worry if you accidentally give your cat more CBD than necessary. Cats cannot overdose on hemp-sourced, THC-free CBD oil. 

Consult with a licensed veterinarian to determine the ideal starting dose of CBD, or use an online CBD dosage calculator. 

How Often Should CBD Oils Be Given to Cats With Cancer?

CBD oils should be administered to cats with cancer daily. CBD is fat-soluble and stored in fat cells. The storage capacity has a cumulative effect, which in turn results in a prolonged presence and effectiveness in the body. 

In simple terms, cannabidiol needs time to build up in the cat’s body. Therefore, it is best used daily. It is up to the cat’s individual needs whether the daily dose will be divided into two or even three separate CBD administrations. 

Use the CBD for at least three weeks to see an improvement. Hemp-extracted CBD products formulated for cats are safe to use daily and up to several times a day. 

How Effective Are CBD Oils in Treating Cats With Cancer?

CBD oils are not an effective miracle cure in treating cats with cancer. However, they are great additions to a multimodal and individually tailored anti-cancer treatment plan. 

Cannabidiol for cats has several anti-cancer properties. It also boosts the efficacy of mainstream cancer treatments and relieves their side effects. 

Current research and anecdotal evidence support the use of CBD for treating cancer. However, “more research is needed to fully understand CBD oil’s role in pet health,” in cancer treatment in cats, explains MetLife Pet Insurance. 

Does CBD Oil Shrink Tumors?

Yes, CBD shrinks some tumors in some animal models and in humans. However, research on the topic is still in its early stages and requires further investigation. 

The use of CBD in mice with melanoma resulted in a significant tumor size reduction, according to a study, “Cannabinoids as a Potential New and Novel Treatment for Melanoma: A Pilot Study in a Murine Model,” published in the Journal of Surgical Research in 2019. 

CBD, even if it does not shrink certain tumors, helps with symptom control. A new 2024 AHVMA study found that cannabis provides “excellent palliative support to a cat with an advanced-stage cancer diagnosis”.

Does CBD Oil Help Treat Lymphoma?

Yes, CBD oil can help treat lymphoma. CBD is not a definitive cure. However, it reduces stress and pain while supporting appetite in patients with cancer. 

Additionally, CBD exhibits anti-cancer properties that may help cats with lymphoma. CBD was found to be effective against canine T-cell lymphoma cells in a study titled “Effects of Cannabidiol, ∆9-Tetrahydrocannabinol, and WIN 55-212-22 on the Viability of Canine and Human Non-Hodgkin Lymphoma Cell Lines,” published in Biomolecules in 2024. 

Specific studies on the effects of CBD on lymphoma in cats are lacking. Most conclusions are derived from research done on other animal models. 

Therefore, it is recommended that you always consult a veterinarian before giving your cat CBD as part of its cancer treatment strategy. 

Is CBD Oil Safe for Cats?

Yes, CBD oil is safe for cats. When used correctly and in the proper doses, hemp-sourced CBD is perfectly safe for cats and kittens over the age of four months. 

The safety of CBD for cats was first confirmed in a study, “Safety and Tolerability of Escalating Cannabinoid Doses in Healthy Cats,” published in the Journal of Feline Medicine and Surgery in 2021. 

A newer 2024 study, “Healthy Cats Tolerate Long-Term Daily Feeding of Cannabidiol,” reached the same conclusion, stating that CBD was “well tolerated by healthy cats when supplemented over a period of 26 weeks.”

So, “Are CBD oils safe for cats?” The answer is yes, but always get CBD supplements specifically formulated for cats. Human CBD supplements contain THC and are toxic to pets. 

Additionally, ensure that use of CBD is supervised by a vet and adhere to the recommended doses and administration frequency. 

Are There Any Possible Side Effects From CBD Oils for Cats With Cancer?

Yes, there are possible side effects from CBD oils for cats with cancer. CBD in cats can cause gastrointestinal upset (nausea, vomiting, diarrhea), drowsiness, increased water consumption, ear redness, and elevation in certain liver enzymes (AST and ALT). 

Licking, head shaking, pacing, chomping, gagging, increased salivation, and vomiting are side effects reported in a study, “Single-Dose Pharmacokinetics and Preliminary Safety Assessment with Use of CBD-Rich Hemp Nutraceutical in Healthy Dogs and Cats,” published in Animals in 2019. 

• Gastrointestinal upset 
• Drowsiness 
• Increased water intake 
• Ear redness 
• Elevated liver enzymes 
• Licking, chomping, and gagging 
• Head shaking 
• Pacing 
• Hypersalivation 

The side effects of CBD are mild, rare, and transient. Most side effects disappear once the CBD dose is adjusted. Using high-quality CBD products minimizes the risk of adverse effects. 

Where Can You buy CBD Oils for Cats with Cancer?

Buy CBD oils for cats with cancer from recommended and trusted, pet-specific CBD brands. Pet CBD products are available over-the-counter and are considered supplements, meaning they are not strictly regulated. 

It is up to you to research the market and make safe purchases. Buy CBD oils from brands that test their products in third-party laboratories. Such brands display a document called Certificate of Analysis (COA) as proof of the independent testing. 

Also, check the ingredient, sourcing, and extraction methods used. High-quality pet CBD should be sourced from organic hemp, contain organic carrier oil, and be extracted using supercritical CO2 extraction. 

What Are the Other Cat Diseases or Illnesses CBD Oils Can Treat?

Other cat diseases or illnesses CBD oils can treat include anxiety, arthritis, seizures, digestive issues, and kidney disease. 

• CBD Oil for Cats with Anxiety: CBD has strong anxiolytic properties, beneficial to cats with anxiety issues. CBD supports natural calmness and relaxation.
• CBD Oil for Cats with Arthritis: CBD reduces inflammation and pain associated with joint problems. Arthritic cats supplemented with cannabis feel more comfortable and are more active. 
• CBD Oil for Cats with Seizures: CBD has antiepileptic and anticonvulsant features. Plus, it reduces neuroinflammation and acts as a neuroprotectant. 
• CBD Oil for Cats with Digestive Issues: CBD can help increase appetite in cats by supporting overall health and alleviating nausea. 
• CBD Oil for Cats with Kidney Disease: CBD eases symptoms associated with chronic kidney disease in cats, such as low appetite, pain, and anxiety. 

CBD supports natural wellness for various conditions. It can also be used as a preventative to boost the cat’s immune system. 

What Are Other CBD Products Besides CBD Oils for Cats?

The other CBD products, besides CBD oils, for cats include CBD treats, CBD capsules, and CBD topicals. 

• CBD treats for cats 
• CBD capsules for cats
• CBD topicals for cats 

CBD treats for cats are super convenient. They are edibles infused with CBD oil and cat-friendly ingredients. CBD treats feature delicious flavors and pre-measured amounts of cannabinoids for easy use. 

CBD capsules for cats are another oral alternative. However, considering most cats are finicky and not easy to administer pills, the capsules are less practical compared to oils and treats. 

CBD topicals for cats include creams and patches. Creams are not always practical for cats. 

Once applied to the skin, cats must be prevented from licking them. Licking the CBD cream is not dangerous for the cat, but it does reduce its effectiveness. CBD patches are a newer topical product. The patch is applied to the naked skin, and once in contact with the body heat, it starts releasing cannabinoids. 

Oils and treats are the top two CBD products for cats. The primary benefits of CBD oil include its rapid absorption and straightforward dosing. CBD treats, on the other hand, are convenient for picky cats who dislike the scent and texture of oils.
