Hello, my 3 year old himalayan is very skinny. I currently feed him "Feline Holistic Select" dry cat food, and as a treat sometimes, Friskies wet food. I started thinking that between his scrawny body and lack of playfulness he maybe needs some extra calories to help him "bulk up" anyone know of any over the counter (read: petco/petsmart) high calorie cat foods. PS I have another cat that is fine and doesnt need the extra umph, so I dont want to switch to a kitten food. just somthing I could fed him as a special treat. thanks!!
