Ooooooo! Yeah - I give them less prozyme than the instructions, and they also say that cats over X age should get twice as much. Most of mine are over that age, so I didn't worry about the additional digestive enzymes in the Vet's Best and decided to keep using the prozyme as well.Oh! LOL. :lol3: And I was wondering about adding additional digestive enzymes on top of what is already in the Vet's Best. They don't actually tell us how much of the enzymes are really in there, do they? They are using 2 mg per tablet of a product called Allzyme.
