Hello Everyone. My cat willis is 3 years old and is a normal weight. Not long after I first got him he developed a urinary tract infection and hasn't had one since (about 1.5 years ago). We have been feeding him purina urinary tract health dry food since that time and giving him purina cat food once in a while (4 cans worth a month). He seems to like the wet food but only eats a little at a time. I am afraid to keep feeding him the same dry food because it is so specific to that 1 health issue. I am concerned he may not be getting the nutrients he needs. any suggestions? I am far from rich but love him to death. I will get him whatever he needs as long as i know what it is. Any recommendations?
