Fleece cleaning

With adequate layers under the fleece to absorb urine I never had a problem with odor. Your cage will have to be swept or vacuumed daily though, to collect tossed around poo's. That really isn't a big issue though, since their poo is pretty much hard.

My 2 pigs are in a large open enclosed area. I use towels under my fleece, and double the towels under areas that they sleep or pee the most. I scoop the poop out daily, usually about 4 times a day, and vacuum to get stray hairs, food crumbs, etc. as needed. I don't have a problem with odor, and change everything once a week.

My hay is on a towel in a corner now.I have used a litterbox with carefresh and pine pellets and it worked well. No odor unless really saturated.

Good luck!
