one of our hammys, the male one (any advice on how to stop this will be amazing) was adopted, and he was a little biter, and we think he never got cleaned by the previous owners and was left to run about in very wet bedding as he was greasey as well as smelly.

but we think he is weeing in his house - but its never wet and his coat is gettin greasey/smelly again

all we do is let him roll in it in his own time twice then he's back in his cage with fresh water (as always) and what not. this was recommended to us cos of how bad he gets.
