That's what I thought....he was just hungry. I haven't fed him in his enclosure, maybe I'll do that tonight.
The first mouse he walked away from was a bit larger, but still smaller around than he was and it felt warm to me (through a paper towel) so I just went with it. I'm afraid of them popping (had that happen once, although he still ate it) so I don't want to over heat them.
I'll try heating them a little extra with a hair dryer tonight and feeding in his cage. Thanks....I'll let you know.
