Well I was sitting in the room with the kittens last night, And 2 of them went to the pan to go poop,and both of them meowed while doing so.. :-/ But after wards was jumping around like a banchie. Was it because they are getting used to going? I looked to make sure the poo wasnt red or anything, and it was kinda firm.. would that be why? Cause it is firm? Is this something I Should be alarmed about?
