We used the industrial mud-rug type carpet as the base for his cage, and it’s been great. I sweep the loose hay (and misplaced poop) up from the floor when I fill his hay bin night before I go to bed. Every couple of weeks, when the shedding gets bad enough to see dark grey fur on a black rug, i do a more thorough cleaning, but I’ve only ever had to sweep. I haven’t tried to vacuum, since he’s not keen on loud noises, but I know the carpeting can be vacuumed if needed.
He’s very good about only peeing in his box, so that hasn’t been a problem. But when he’s annoyed (or hot, in the summer), he’s been known to dump his water dish. I soak up what I can with paper towels, but since the carpet is designed to deal with the crud people track in from outside, getting wet isn’t really much of a problem.
His space is too big for us to try to get the carpet out to hose it down, so going with something industrially durable seems to have been a good decision for us.
