I now free feed my 3 cats dry food only. I measure it out each day so that I don't give them too much. I used to feed them dry mixed with wet food twice a day. When Pepper was a kitten he was also a bottomless pit. He ate wet and dry kitten food. When he got older I made the mistake of putting too much dry food in their dish. Pepper gained a lot of weight. The vet said that some cats will over eat. I never knew that before because I never had a problem with Storm. I always thought that dogs were the ones that would over eat. Pepper is still a big boy and weighs about 17lbs but he is also big boned and muscular. Now I measure out their dry food each morning and I don't refill the dish until the next morning. They only get treats on weekends. I buy the 20lb bags of food and it seems to last a long time. Good luck.
