I am not sure what the healthy weight for an adult male cat should be. My boy kitty weighed in at 11.8 pounds on his most recent vet visit, and he is only 1 1/2 years old. The vet did not say anything about him being too chunky, but I wonder if he is getting too big. He feels very solid (if that makes sense) when I pick him up.
My petite 5 year old female cat barely weighs 8 pounds.
