I have 2 boars that are housed separately one in a zoozone and the other in a C&C cage until we get another zoozone. I would like both of them to live together as they both get on fine. Anyway it is costing too much buying woodchip every week and I was wondering if there's anything else I can use for bedding like a blanket or somethin. My older guinea pig Misty keeps getting sores on his mouth and we aren't sure if its from the wood chip (he's been to the vet and been give antibiotics twice) so if there's anything else I can use I would appreciate it if someone could help.
