I have one kitty that is a bit on the pudgy side (ok, he's kinda fat) and the vet said not to free feed him. I have another cat who is sooo hard to keep weight on and the same vet said to free feed him. I live in an apartment and there is no way to restrict one and free feed the other. So, I free feed a grain free dry and limig their wet to morning and night. My skinny cat is putting on weight and my plumper may have lost a little bit of weight on this diet. What I have noticed is that they are both way more active than they used to be and that is good.
