I have called my fat cat (22 lbs of tuxedo) Mr. Piggy when he tucks into a meal, makes eating noises.
I also have a hard time not poking, or rubbing his belly, calling him Buddha belly kitty.
Have not seen him in a month. He has lost some weight, now that he is an outside cat, but he has buffed up. I'll need to be careful, he may take a finger if I poked him now.
