Geelin 2 Pack 26" x 13.5" Corrugated Plastic Cage Liners Base 1 x 2 Panel Size Guinea Pig Cage Liner for Guinea Pigs Hedgehogs Rabbits Applied with C&C Cages, White

I use a a litter box from Amazon, lined with a disposable litter box liner, a puppy pad, and pine litter pellets from tractor supply. This lasts 4 days with 4 pigs. https://a.co/d/0dsgj5wi For laundry, I use a free and clear liquid detergent mixed with oxi clean powdered on a long cycle with hot water and an extra rinse. If u don’t want to use oxi clean, use a cup of vinegar instead.
