I read somewhere, can't remember where, that you have to watch how much cardboard you give your chins. I hadn't ever really thought about that but I guess it makes sense. I'm anxious to know because my second chin, Tuvok, has had a poop change. His have always been smaller than Herby's but now they're really small; though still soft/firm and healthy looking.
To give you an idea of his situation he recently broke his cage and I'm in the middle of making him a new one just waiting on shelves; so now he's in the boy's playpen and did infact have quite a bit of cardboard in there with with him: a large cardboard box, 2 cardboard tunnels and some wood chews with pine shavings for bedding. After reading that I took out one of the cardboards tubes put another wooden house in there, though he doesn't like to use it he just stands on it, and put a piece of board on the bottom of the cardboard house. I've also but alot more wood chews in with him so hopefully he doesn't chew the cardboard as often. Another thing his hay was on the ground and he was refusing to eat it, but now it's hanging and he's eating more and I think his crap is getting a bit bigger...but I want to be sure of the cardboard thing to know if I should start watching that. Herby and Tuvok are pretty much always around cardboard and have some to chew on. Thanks.
