The rats get their cage cleaned thoroughly once a week, and spot-cleaned every evening. I may need to start doing this more often until the babies are in their new homes. ^_^

I scoop out the lizard's poop as soon as I find it, but she only gets the cage thoroughly cleaned about once a month.

The snake gets her cage cleaned every two weeks.

The mouse gets his cage cleaned once or twice a week, depending on how stinky he gets. ^_^

The betta gets about a 50% water change once a week, and a thorough cleaning every two months or so.

The other fish get a 50% water change twice a month.

I have the horrible feeling that I'm forgetting someone.....
