We began giving our older cat Vitality’s Enzymes about four years ago and have not stopped. He was having lower GI issues and being he is older we were also looking to generally support his immune system (good bugs in his gut) and Vitality’s Super Pet Enzymes help with both. Vitality will tell you and I agree it also matters what you feed your pet when you give him this – it is not some wonder drug – but it supports good health. We sprinkle it onto his moist food daily. Full disclosure, my cat does love food, but is put off by new smells placed onto his food. He won’t eat anything he doesn’t like or isn’t familiar with – from the first he never bat an eye at his food with this product. I don’t think it smells or tastes like much of anything to him. We have run out without having a new bottle handy and his lower GI tract woes returned. We’re pleased. We have been giving this to him, regularly now, for about four years. We’re loyal customers now.
