Angel was a rescue hamster, I got her at age 8 months so I don't know what her living conditions were like prior to that, but she lives in a Hamster Heaven and uses the penthouse bit for sleeping, storing food and as a toilet. This means that she stores her food, then pees and poos on it, then sleeps in the same area (yack). I clean the penthouse out every day, sometimes twice a day but this means I go through a lot of food, the main problem is that she smells bad so obviously she isn't clean. Has anyone else encountered this and has anyone got any ideas to stop it. I removed the penthouse at one point and she just did exactly the same in a corner of her cage. Oh she already has a sand bath but she just uses it as a play area and not a toilet.
