Yes, I also have used it for both cats for respiratory virus. However, it should used with caution...each cat is different in terms of levels of sensitivity. I used it successfully on my Domestic Short hair (saved his life). However, my Ragdoll female developed Clostridium Dificile. Which means the Goldenseal killed too much of the good bacteria, in the intestine. That resulted in a permanent condition manifested as episodes of bloody stools because the bad bacteria overtook, and attacked the intestinal lining. There is no cure and the only treatment is Flagyl, which in turn causes food allergies to grains and carbohydrates.
