I have a small 1 gal tank vac to use to suck up their poos and hair. The only time if I have to change it sooner than that is if I had a pigloo or a towel drapped to cover a corner. They tend ot pee there alot. So I stopped giving them those 2 things. They have cozies that I make and sell, Also their hay rack is a litter pan with hay and woody pellets that are bedding. They are up there majority of the time.
Ah. My pigs do tend to poop a lot in their "tent" house. I just recently made a fully boxed in hay box for them. They do seem to realize it's a good place to eat and poop! Silly piggies.
