Unlike my rats, my mice are doing wonderful! I am finding though, that they love to chew. I try and give them cardboard to chew, but that doesn't last long with them. Chew sticks and blocks at pet stores are expensive and don't last but so long. I was wondering if sticks from outside could be used as chew sticks if they were sanitized. I've heard of people wanting to use branches as reptile tank decorations baking the wood in the oven to kill bugs and such. Could this be done for chew sticks found outside? If so, how hot and how long do you bake?
