Another question, not dog related. I've done some reading, and it states that it is benifical to some cats, to help with hairballs. One of our cats is in papaya every day to break apart the hair in her stomach, and gets a laxitive to coat the hair in the stomach so she can pass it out. If we miss a few dosages of papaya, she'll start throwing up her meals, because the hair builds up in her stomach very fast. We do groom her to release hair, but she grooms herself more than a normal cat, and as well, she doesn't throw up her hair balls (you'll see her coughing and gagging, then it'll come up, and she'll swallow it again). Is there different types of prozyme, or is it one bottle that is used for every animal?
