Apparently, Buzz is ticked off because the Bowl Of Food is not full to overflowing. There is at least one cup of dry food in there. If he ate all of it, he would explode. It is, quite simply, in his opinion, Not Good Enough. Boy, am I glad that my DH managed to find out how he was escaping from the basement at night and blocked off his access. I was getting really tired of being trampolined on the hour, every hour, from 3 a.m. on...!
I just know that the vet is going to tick me off for all of the weight he's gained. In my defense, I didn't realize that he was eating a great deal of his deceased older sister's food. He's an opportunist, the little pest. Now he just steals his brother's food, since Deke is a grazer and Buzz is a "let's eat everything until somebody needs to call for an ambulance" type of guy.
