His floors are covered in a towel with Y'sN for his litter box. The carpets on the floor are vacuumed frequently and I don't use air freshners or Febreeze or that sort of thing in my room (where is his cage is). I'm going to see about an unscented detergent - I've never thought about that before. I can't smell anything on his towels but perhaps he can. Thanks for the input
