My two Burmese boys are suddenly acting like they've never been fed. Jumping up to eat cheese left for a milisecond on the side, tripping me up in the kitchen all the time, yowling at me. And the one of them that we used to hardly see is around all the time. I think it might be that he had another source of food which has now dried up because I'm feeding them the same food and nothing has changed here. Or maybe it is a 'fatten up for the winter' thing. I don't remember them doing it last year though (they're only 2). Has anyone had the same experience?
