10 Best CBD Oil Alternatives for Cats with Cancer in 2021 – Reviews & Top Picks

If you’ve landed on this page because your beloved animal is suffering from cancer and you want to bring them some pain
relief, our hearts are with you. While CBD oil has become somewhat of a breakout solution for pain in humans and even in animals, it isn’t consistently regulated by the FDA, and the lack of regulations can be a safety concern for cat owners interested in using natural products like this.

Fortunately, there are several alternatives to CBD oils. Hemp oil, or hemp seed oil, is the most common one. Both CBD oil and hemp oil come from the cannabis plant, but they’re different products.

Hemp oil is mostly an extraction from hemp seeds and contains little to no cannabidiol (CBD). Meanwhile, CBD oil is an extraction from the leaves, flowers, and stalks of the cannabis plant.

If you have a cat already experiencing the effects of cancer, the last thing you want to do is introduce something that can produce more adverse side effects. Therefore, it can be safer to try other natural products that have more regulations on them.

We have reviews of some of the best hemp oil for cats and other CBD oil alternatives. Make sure to read through each one to find one that can help manage your cat’s symptoms.

The hemp seed oil in this supplement can help with reducing inflammation, which is a known factor that can contribute to cancer. Krill oil is high in omega-3s and astaxanthin and can help boost a cat’s immune system. Salmon oil can nourish a cat’s skin and coat and also help with alleviating joint pain.

A team of veterinarians formulated this supplement, and it now gets manufactured in an FDA-approved facility that’s in line with Current Good Manufacturing Practice (CGMP) regulations. Therefore, you can feel confident in knowing that you’re giving your cat safe ingredients.

 Volume:  2 fluid ounces

If you don’t see your cat experiencing the benefits of hemp oil, you can try using other natural products that help alleviate pain. Pet Wellbeing Comfort GOLD Natural Herbal Supplement for Pain combines five active natural ingredients to specifically address pain.

Veterinarians formulated this combination of ingredients, and they’re ethically sourced. The formula doesn’t contain any preservatives, GMOs, or synthetic ingredients. It’s also gentle on the stomach, so it’s a great option for cats having difficulty ingesting foods due to cancer.

You might have to get a little creative with getting your cat to eat this supplement because it has unfamiliar smells. However, it comes with a convenient dropper so you can put a discrete amount in their food or favorite treats.

Overall, we love this supplement because it directly addresses pain management and can help your cat move and walk around more easily.

4. Hemp Well Hemp Omegas Liquid Cat & Dog Supplement – Best for Kittens

Hemp Well Hemp Omegas Liquid Cat & Dog Supplement (1)

 Volume:  2 fluid ounces, 16 fluid ounces, 1 gallon
 Active Ingredients:   Hemp oil, omega-3, omega-6

Unfortunately, there are rare cases where kittens can have cancer. Since kittens are still in their developmental stages, it’s extremely important to make sure that they only consume the safest ingredients.

Hemp Well Omegas Liquid Supplement is GMO-free and only uses organic ingredients. It contains omega-3 and omega-6 fatty acids to help boost your kitten’s immune system and reduce inflammation. The hemp oil also helps with reducing stress to keep your kitten calm.

We also love that this supplement has a long shelf-life compared to other oils that have omega fatty acids, such as flaxseed oils. These supplements can barely last a year, but Hemp Well’s supplement is effective for up to two years. It also doesn’t contain any strong smells, so your kitten will barely notice it.

The only downside that we can find to this supplement is the packaging. The 16-ounce bottle tends to leak, so you might have to put it in another bottle to reduce waste. Other than that, this effective formula is one of the safest hemp oil options for kittens.


  • Organic and GMO-free
  • Reduces stress and inflammation
  • Long shelf life
  • No strong smells

This formula is also safe for cats of all ages, so kittens and older cats can use it. It mainly targets inflammation and anxiety and distress. Therefore, if your cat has other symptoms, such as nausea, this product may not be the best option for them.

The formula is also very strong, so it’s important to give the correct dosage to your cat. Unfortunately, the label has very small print, so if you want a clear reading of the instructions, you have to read the online copy.

  • Only targets specific symptoms
  • Difficult to read instructions

Buyer’s Guide

When you’re shopping for natural pain supplements for your cat, it’s important to find the right blend or formula because some ingredients can interfere with any ongoing cancer treatments. Cats with cancer may also have sensitive stomachs and weak immune systems, so they need supplements that won’t further irritate them or make them feel sick.

Here are some things to consider while shopping for CBD oil alternatives for cats.

Active Ingredients

Pain supplements usually contain several active ingredients. These ingredients can help alleviate pain, boost the immune system or soothe upset stomachs. Common active ingredients include the following:

  • Hemp Oil
  • Fish Oil
  • Turmeric
  • Omega fatty acids
  • Chamomile (in small doses)
  • Glucosamine and chondroitin
  • Traumeel

Some of these ingredients can help with pain management by alleviating stress and producing a calming effect. Others have anti-inflammatory properties to reduce pain and irritation. Most cats don’t have allergies to these ingredients.

However, if you have a cat with cancer, it’s always best to consult with your veterinarian to make sure that they’re safe for them to use. It’s better to be safe than sorry.

High-Quality Ingredients

Cats with cancer can have weakened immune systems and sensitive digestive tracts, so it’s important to use high-quality ingredients. Try to look for formulas that contain organic and non-GMO ingredients. Avoid artificial flavoring and preservatives because these can further irritate your cat. When applicable, try to verify if a supplement uses human-grade food.

If you’re interested in using hemp oil, try to look for food-grade hemp oil to ensure that it’s safe for consumption and not just topical treatment.

Simple Blend

Some ingredients can interfere with the efficacy of certain medications. Therefore, it’s important to have good communication with your vet when you want to introduce a new supplement to your cat’s existing regimen.

As a general rule of thumb, the simpler the supplement, the better. Therefore, before you buy a supplement, try to identify the exact issue your cat experiences. For example, if your cat has an upset stomach, find a supplement that specifically treats that symptom. The last thing you want to do is overmedicate or complicate your cat’s medication and treatments.

A simple blend without any fluff will also help you identify culprits quickly if your cat starts to exhibit new symptoms. Therefore, when it comes to cats with cancer, oils, and liquid supplements will be a safer choice. Chews usually contain fillers and binders to keep each piece intact. Some of these binders, such as sugars and potato starch, can cause an upset stomach for sensitive cats.


Out of all our reviews, Naturvet Hemp Liquid Supplement is our favorite choice. It combines nutritious active ingredients with hemp oil to provide both comfort and nourishment for cats. Pet Wellbeing Comfort GOLD Natural Herbal Supplement for Pain is our favorite runner-up because it uses all-natural ingredients that also don’t irritate the stomach.

Overall, natural supplements can help alleviate pain for cats with cancer. Make sure to work with your veterinarian to find a blend that addresses their pain without interfering with other treatments.
