Quinn and Sasha are getting older and I undertand that their metabolism slows but their starting to get fat. They can still roll in a ball so they aren't too big yet but I want to make sure that doesn't happen. I've already introduced weight control cat food and since I've introduced it is now over half of their food. However, they haven't lost any weight. I try to get them to eat fruits and vegetables but no luck so far. They only eat chicken and it has to be dark meat, white meat is rejected. They're both going to the vet soon and I know Dr. Munn will mention their weight and I feel bad. Any suggestions?
