Two timing cat

My cat Gatsby is hilarious. He has huge saucer green eyes, waddles like an overstuffed goose and instead of a meow he says "meep!" He's been growing fatter for sometime now, and it didn't make one dent when I switched to diet food. He's gone most of the day, but always comes in for a good scratch behind the ears at night -- we always refer to him as our college kid, wandering restlessly all hours of the day and night, but always coming home for a snack and a hug when he needs it. We've been suspecting that he's been two-timing us for sometime now -- and tonight we got proof. Ryan brought him into the bedroom where I was working and he was laughing so hard he could only get out "look!" And that's when I saw the bright red brand new collar with a nice little name tag that read: CHUBBLES. HAHAHA!!! Chubbles the cat. It's actually the perfect name for him in her current shape. We called the number on the tag and as of this post, haven't heard back yet. Hopefully we can figure out how to put him on a diet between our two families. Although I'm sure that somehow Gatsby Chubbles will just find some other family to feed him if we do. Such a galavanting moocher, that cat!
