Gilbert's been active all week but as of Thursday night, I took out and put in new water, and the next day he was slow moving and almost looked tired. Now he won't even eat. I just recently started feeding him carrots, maybe that's the problem? He had surgery last month for an ear infection-abscess, and he recovered just fine if that's any help.
