In our 5x2 area we usually have two 3x2 fleeces overlapped a bit. Thats quite helpful in many ways because two 3x2 fleeces balance in the washing machine to spin properly, also most fleece cage liners shrink a bit/crinkle at the edges after a few hot washes- a once a month hot wash at 60 degrees as a minimum is usually needed to kill bacteria and remove stubborn pee stains and odours, and after any illness or suspected mites or lice or new pigs joining, a hot wash is always a good hygiene measure. And with 3x2's you can mix and match, just change one end of the cage if it is noticeably wet or poopy, or just shove the piggies onto the other end of the cage while you quickly shake the poops off!
