High humidity!

[Albert Clark]

My CB70s are the exact same way if I stick an accurite in them. I'm guessing most are that way, I see plenty of racks of cb70s with no ventilation holes in them with no ill effects.

I think most of the issues associated with higher humidity are related to cages that are sopping wet and not kept very clean. (I could be wrong)

Thanks, I was using a product in the tub called Kay-t small animal bedding that was left over from an earlier time. It was very little in the tub but I think that was the problem. I did what dvirginia said and wiped out the tub with a towel . That seems to have helped. I put in some fresh paper as the temporary substrate. Thanks again!
