My ferret has a playroom, with a few toys that can be easily cleaned. However, he also has a maze made out of Capri Sun boxes. Somehow, fleas got in his playroom (no clue how, none of the other animals are allowed in there & are all treated for fleas).
Is there a safe way to de-flea the room, most importantly his maze? He does get plain Advantage every month, so I'm so concerned with them biting him as I am with them just being there (& climbing all over me when we're playing)
