Well like a lot of things in my life when it comes to weight of my cats it has varied a lot. Right now out little guy is probably the most fit cat that I have ever seen, and I never would have thought to describe a cat as muscular, but this guy is coming pretty close. That said, though, out last cat was quite the opposite towards the end. He ballooned up when he started to lay around all day, and event the vet told us to get him out more, but we just let him out which we thought was good, but then he would just go hide under the bushes and eat some more. Not much you can do, though, except try. Thanks for sharing.
