I'm just curious. I have the opportunity to live the life of the early 1800's for a few months, and I argued with my mom that I was not going unless I could take my rats. She doesn't get that, of course, but I argued that she would never care for them like I do.
So how DO I care for them, she asks.
Every day I pick up the thrown food and do poop patrol

. I wipe down any badly peed bars and corners. They get play time, treats, and loving every day (I think this needs little to no elaboration).
Every Friday I do a complete scrub-down. I can't STAND having my girls live in a pee-dribbled cage. I put the girls in their play area, put the old bedding in the laundry basket, and toss the litter pan contents. All their soakable items go into the tub for cleaning. Then the base and pull out tray (bird cage) go in for a soaking and I scrub everything down. I take it out, wipe it off, and then I put the cage top in the tub and spray it down with cleaning solution. I let that stand while I go wipe down the stand their cage rests on, and the wall (they're talented at peeing down the wall). Then I scrub and clean the cage bars, making sure I get -everything-. It gets dried off (a chore, I tell you) and the cage is reassembled. Then the girls get a bath! They dry off with me on my bed, and then they get back in their cage for food and water and bathroom stuffs. While they're in their cage I take care of the laundry and clean the tub since my family is so weird about my girls being in the tub.
Total cleaning time: 1-2, maybe 3 hours.
