what do you keep rats in?

[BoidKeeper]

I use the roughneck rubbermaid. I line it with 1/4" metal mesh forming a metal basket. I cut a lare portion of the lid out and line it with the same metal mesh. Then I make a feeder out of the same mesh and attach it to the lid. That way I never have to remove the lid to feed them. The water bottle is attached to the outside much like in Linds pic. When it comes time to clean I lift out the basket and out come the mess with it.
Cheers,
