Thank you everyone for your input on this. I have to agree that it is most likely food related. Looks like a new diet will be in order. I will make an appointment with my vet just to have Willy checked out and see what he recommends food wise.

Abby Mom; Yes, I would say that Willy could be part Main Coon.

Randy K; I wouldn't say very active, but active enough. Especially at 2 in the morning.

CraftLady; We have stores that I guess are similar to Petsmart and Petco. They are called Pet Nature and Mondou.

Lori; You must tell me what the vet has to say about my girl Rumor and about Rocky. I also free feed my guys. They get two scoops in a bowl a day for the 5 of them.

Kim; It's uncanny how Rumor, Fuzzy and Willy look alike.

Thanks again for your opinions.
