Cancer in Cats: What I Would Do for My Own Cat

Feline cancer is difficult to treat. Some types carry a very poor prognosis. But there are new developments, along with holistic options, that may give us more tools than we had before.

If my own cat were diagnosed with cancer, here is exactly what I would consider.

A New Breakthrough for Feline Squamous Cell Carcinoma

A recent study from UC Davis looked at a new treatment for head and neck squamous cell carcinoma in cats. This is one of the most aggressive feline cancers, and historically survival time has been very short.

Researchers developed a drug that targets a protein called STAT3. This protein helps cancer cells grow and spread. By blocking STAT3, they aim to slow tumor growth.

The results were encouraging:

• Over one third of cats responded well

• Average survival time in responders was about 160 days

• Side effects were minimal, mostly mild anemia

Five months is not a cure. But compared to only weeks of survival, it is meaningful. If my cat had squamous cell carcinoma, I would seriously consider this STAT3 inhibitor.

Holistic and Repurposed Options I Would Also Consider

Alongside conventional care, I would look at additional support.

1. Fenbendazole for Cancer

Fenbendazole, also known as Panacur, is a long used dewormer. Research has explored its anti tumor effects across multiple cancer cell lines.

Some studies suggest it interferes with cancer cell metabolism and growth.

Typical dosing often used in practice:
50 mg per kilogram
Given 3 days on, 4 days off

It has a wide safety margin and minimal side effects. If I saw any positive response after a month, I would continue.

2. Ivermectin as an Adjunct

Ivermectin has also been studied for anti tumor properties. Research suggests it may:

• Slow tumor growth

• Inhibit spread

• Induce cancer cell death

• Support immune recognition of cancer

There is no established feline cancer protocol. Any use should be discussed with your veterinarian. If I were considering it, I would use conservative doses similar to parasite treatment regimens and reassess monthly.

3. Cannabinoids for Cancer and Pain

Cats have an endocannabinoid system, just like we do.

CBD and other cannabinoids such as CBG, CBC, and CBN may:

• Reduce cancer related pain

• Support immune function

• Influence tumor growth pathways

CBD has the most research. Higher doses are often needed for cancer support than for general wellness.

I would start at:
3 mg per 10 pounds twice daily
Then increase gradually if tolerated

Whole plant blends may offer broader support due to additional plant compounds.

4. Curcumin and Feline Metabolism

Curcumin, the active compound in turmeric, has strong anti inflammatory and anti cancer properties.

Cats metabolize compounds differently than dogs and people. Research suggests 95 percent curcumin may achieve higher blood levels in cats, potentially increasing its effect.

Typical dose:
100 mg per 10 pounds daily

Curcumin may help reduce inflammation and support cancer cell control.

5. Melatonin for Immune Support

Melatonin is more than a sleep hormone. It is a powerful antioxidant and immune modulator.

Research has shown it may:

• Enhance immune response

• Promote cancer cell death

• Improve outcomes alongside surgery

One published case described a cat with mammary carcinoma who lived over two years after surgery while receiving 3 mg daily of melatonin. Most cats with this diagnosis survive less than a year.

Melatonin is inexpensive and very safe. If I had to choose one supportive therapy to add, this would be high on my list.

What I Would Do

If my cat had cancer, I would:

• Consider surgery when appropriate

• Explore new targeted therapies like STAT3 inhibitors

• Add safe adjunct options such as melatonin

• Consider curcumin and cannabinoids

• Discuss repurposed drugs like fenbendazole with my veterinarian

There is no single magic cure. But combining thoughtful conventional care with carefully chosen holistic support may offer more time and better quality of life.

I truly hope your cat never faces cancer. But if they do, know that there are options to consider.
