We usually have 15 young raccoons in the clinic each spring.  They use towels for bedding, usually a big one folded on the floor of their container and another smaller one to cuddle in.  It's the same for the 18 little squirrels and the 23 young opossums. All little mammals have towels for bedding and are usually housed in small groups.   I remember one day a few years ago when the washer broke down in the morning.  By the time it was fixed at 6pm we had 8 huge loads of dirty towels piled up around the washer.  That's a lot of detergent used every day.  We use liquid detergent, although I hate how many plastic bottles I drag off to the recycle place at the landfill!  For my own personal laundry I have begun to use the little dissolving pods of detergent - I like the less waste aspect of them!
