The very day I got the email for Nutra Thrive, I was getting ready to do some research to see if it was safe to give my cat natural supplements. She'd be vomiting close to 3 times a day. She also has some arthritis in her hind legs. I wanted to give her at least a month trial before I gave a review. The first thing I noticed was that it smells good and apparently tasted good since she ate it right up. She is no longer vomiting as much, although it's not completely stopped. I have noticed she is a bit more spunky - for a 15-year-old cat. She still has trouble jumping up, but I don't think she's having as much trouble as she was. I plan on keeping her on this since I think it's helping.
Bottom Line: Yes, I would recommend this to a friend
