Benefits of CBD for Cats (including cancer):

Tips to Maximize the Benefits of CBD Oil in Cats

Here are some tips to help you get the most out of your CBD oil experience:

  • The entourage effect is an essential factor to consider when purchasing CBD products. Isolates only benefit those with specific medical conditions, but full-spectrum oil can help relieve pain and inflammation.
  • For those who need a higher CBD potency, look for 4 mg per ml or more products.
  • Use CBD oil sublingually or at least in your mouth to maximize its absorption.
  • CBD oil is a much greater healer than edible cat treats. Therefore, edibles should be used to compliment your pet's treatment with CBD, not as an alternative or replacement for it.

The Difference Between CBD Oil & Standard Treatment 

Cat cancer is a very similar condition to human cancers, and surgery may be the best option. Cancer-related lumps or bumps on cats often respond well with treatment because their bodies are used to fighting off foreign cells.

The cancer treatment can be either chemotherapy or radiotherapy. Chemotherapy includes medicines designed to kill fast-growing cells, while radiation therapy focuses on shrinking tumors.

There is currently not enough evidence that CBD can be a cheaper alternative or work alongside standard medical therapy. However, despite this fact, it still has promise and may help in some cases of cat cancer.

The Key Takeaway 

Cats are just as susceptible to cancer, though its prevalence in them may not be as common. Symptoms, when they are stricken with the disease, can include persistent sores or lumps that change in shape and size without explanation for bleeding, loss of appetite, etc.

If your cat is suffering from cancer, do not give up hope. Many medications can be bought to help alleviate these symptoms, even though they may have adverse reactions on humans.

Many pet owners find that CBD offers them relief of pain and inflammation, not just for humans but also for cats. In addition, with less THC than what's found in other cannabis products available on the market today, it can be easier to manage conditions like cancers or anxiety without side effects.
You can browse our list to find one that suits your preferences accordingly, but Receptra Naturals brings the best CBD oil for cats with cancers and other conditions.
