Cancer in Cats

Symptoms, Causes & Natural Remedies

Feline cancer is one of the scariest diagnoses a cat parent can get. More than 6 million cats are diagnosed with cancer every year. Cancer in cats can be caused by different factors and affects various areas of the body. This guide will provide help for feline cancer and explore the symptoms, causes, and natural remedies/protocols for this disease from experts in the holistic pet industry. 

Symptoms of Cancer in Cats:

Unfortunately, cats may not show obvious signs of cancer until the disease has advanced. However, there are some symptoms that cat parents should look out for, including:

  • Abnormal lumps or bumps
  • Sores that do not heal
  • Loss of appetite
  • Weight loss
  • Lethargy
  • Difficulty breathing
  • Persistent coughing or wheezing
  • Vomiting or diarrhea
  • Difficulty urinating or defecating
  • Changes in behavior

If you notice any of these symptoms in your cat, it is important to take them to a veterinarian for an evaluation.

Causes of Cancer in Cats:

There are different factors that can contribute to cancer in cats, including:

  • Age: Just like humans, cats are more susceptible to cancer as they age.
  • Genetics: Some cat breeds have a higher risk of developing certain types of cancer due to their genetic makeup.
  • Environmental factors: Exposure to toxins, secondhand smoke, UV radiation and even lack of exercise can increase a cat’s risk of developing cancer.
  • Diet: Feeding your cat a diet that is high in carbohydrates, low in protein, or contains artificial preservatives and additives can increase their risk of cancer.
  • Stress: Chronic stress can weaken a cat’s immune system, making them more vulnerable to cancer.

Natural Remedies for Cancer in Cats:

Holistic veterinarians often recommend natural remedies as a complementary therapy for feline cancer. These remedies may help to alleviate symptoms, boost the immune system, and improve the overall health and well-being of your cat. Some general natural remedies to help cancer in cats include:

  1. Diet: A balanced, species appropriate, fresh food diet that is high in protein and low in carbohydrates can help to support a cat’s immune system and overall health. Avoid feeding your cat processed foods, as they may contain artificial preservatives & additives and can exasperate cancer issues. Stick to cool proteins like fish, rabbit, pork or turkey to reduce inflammation.
  2. Supplements: Certain supplements, such as medicinal mushrooms, omega-3 fatty acids, antioxidants, and probiotics, may help to support a cat’s immune system and improve their overall health.
  3. Acupuncture: Acupuncture can help to alleviate pain and reduce inflammation associated with cancer in cats.
  4. Herbal remedies: Certain herbs, such as turmeric, milk thistle, and echinacea may have anti-cancer properties and can be used to support a cat’s immune system.
  5. Full Spectrum Hemp Extract (CBD) oil: A Full Spectrum Hemp extract with naturally occurring cannabinoids including CBD and THC has already been proven in clinical research to stop the proliferation of cancer cells, stops metastasis, cuts off blood supply, and kills cancer cells. It can also help to reduce inflammation, alleviate pain, improve appetite and support the immune system in cats with cancer.

After treating multiple pets with cancer, autoimmune diseases, seizures, degenerative diseases (old age) I found a lot of similarities which is why it was so easy for me to create products. I learned the biology and therapeutic uses of cannabis – and no other plant or fungi came close to what cannabis does in our bodies. It’s easy to simplify with cannabis and mushrooms because they contain more medicinal properties than any other medicinal plants/herbs and become more powerful and synergistic when you combine them. 

For Adult Cats with Cancer (9 yrs & younger):

  1. Diet: A raw, species appropriate diet of cool proteins and veggies.
  2. Mushrooms: Full dropper of Vitality mushroom extract in PM (contains all the mushrooms that help with these ailments).
  3. Hemp: Full Dropper of Heal hemp tincture or the EASE Horse tincture depending on how aggressive/painful the cancer or disease is.  
  4. If there’s a tumor: Apply SOOTHE salve to it daily. 
  5. Water: Add Silver Hydrosol (Sovereign Silver) to filtered water.

For Senior Cats with Cancer (10+ yrs):

  1. Diet: A gently cooked, species appropriate diet of cool proteins and vegetables (rabbit, pork, broccoli sprouts, cranberry, whitefish), recommend once a day if possible.
  2. Mushrooms:
    • Full dropper of Clarity in AM – for brain support
    • Full dropper of Vitality mushroom extract in PM (contains all the mushrooms that help with these ailments).
  3. Hemp oil: Full Dropper of Heal hemp tincture or the EASE Horse tincture depending on how aggressive/painful the cancer or disease is.
