Hi! as some have asked, how easy is it to clean? Our fleece is designed to be washable and durable through those many washes! We recommend spot cleaning daily as that is a requirement for guinea pigs to stay in a hygienic environment. This means sweeping or sucking up their lil poos especially in their houses or in beds. By properly cleaning your cage you will have a pretty easy time with cleaning the fleece! Just brush it off into the cage/bin and move to the washing machine. Cold water and unscented detergent does the trick and keeps it from bothering their small nose. No liner should remain in the cage longer than 1 week to prevent ammonia build up.
