I just started using old towels for my BP. So far since I have so many old towels I have just cut the pieces I have needed and thrown them away.
When I run my towel supply down a bit I am planning on washing them and reusing them. My BP really seems to like them but then again who frikkin knows LOL.
I know I like them! But they wouldn't be good for colubrids in my opinion. To many changes.
