Our FeLeuk Kit is designed to help cats who are battling feline leukemia virus (FeLV)  - naturally and effectively. By combining CATalyst and Vira-X together in your cat's daily diet, you'll both fight the virus at the core and build a strong immune system - with no toxins or chemicals that will threaten the healthy function of other essential organs, like the liver and kidneys.

Doubling the recommended dosage for the first week is recommended for faster results.

    I have not tried the combo pack with catalyst yet, I initially bought just the vira-x. The vira-x seemed to slightly improve symptoms in the beginning, but by the end of the bottle my cat seemed back to same symptoms. I didn’t have the success everyone else did. I bought this combo pack to see if the catalyst helps build his immune system and to give it another try. Haven’t had enough time to see if it works yet. If symptoms don’t greatly improve, probably won’t purchase again.
