I have a 3 week old rat that I have been raising. I noticed just now his belly feels a bit distended. He just got switched to lab block mush today. He does have poo in his cage (cleaned it this morning so it's recent) and he just peed on me but I'm concerned. I've been struggling to get him hydrated the last week because he weaned himself. Is this just bloat from actually eating/drinking enough today? He really chowed down on the mush. And he is a capped reddish grey rat with a white spot on his forehead. Black eyes
