I wash the rat cage once a week, once and a while I will spot clean in through out the week. I wash the hammocks once a week, or if they aren't too smelly/soiled I will wash them the next week. I scrub the hid boxes and plastic tubes once a week also.

The boys also get a bath once a week, because they are so oily. LOL. The girls get a bath once and a while too, especailly if they are really stinky. hehe.
