I have 2 boys in one cage, they are very good at hitting the litter pan, their fleece is in the cage 4-5 days max. I shake them out into the compost and try to get as much hay off as possible. Then I take them to the laundry mat and wash them on hot with my regular laundry soap, 7th Generation unscented. Every 2 or 3 weeks they get a soak in vinegar water before the washing. Sometimes I will hand wash them at home too. They are always hung on the line to dry, but the final spin usually gets them mostly dry, so the bathroom towel bar works too. Sometimes between washing I'll try to vacuum up the hay and poos on the fleece, but I usually just end up picking it all up by hand (I need a new vacuum).
