i couldnt actually see any pee in the bedding on the floor of his cage, but then when i opened his "sleeping home" it absolutely stank of pee - so i guess thats where all the water he is drinking is going :P anyway he is eating well and everything is going great!
also just wanted to say today is the second day i put him in his wheel and he is running around the room like crazy in his wheel, i swear he is really clever yesterday was his first time and he didnt have a clue what to do so i pushed him a little in his ball but today he racing around everywhere! and bumping into the wall, door etc...but weirdly he is not scared when that happens! so i'm enjoying this and i never knew taming a hammy could be so much fun, this is my first time in having such a young hamster
