Personally, I'm rather suspicious of this product and wouldn't waste my money until more is known about it (the company that makes it won't disclose the ingredients). Their so-called "study" (self-published) was extremely small (19 cats) and there were no controls in place. As well, they appear to be targeting desperate CRF cat caretakers by doing a big internet blitz, targetting message boards, creating Facebook profiles, and emailing rescue groups, claiming RenAvast has helped their cats but failing to disclose their financial interest in the product. Buyer beware.
