Today I come with this question about exercise balls. It's easy to find information about wheels but I can't find much about exercise balls. Are exercise balls OK for mice? I have the idea that I read somewhere they are not so good for mice, but I also read that they can be a lot of fun for them.
The thing is, my mice have a cage with plenty of space to run, and I let them have play time outside every day, but I have one girl that really is an explorer. About 1h in the playpen and the others kind of start asking to go back in the cage, but Mintaka...
She enjoys being in the playpen, and she loves when I take her out in the evening and let her be on my shoulder while I prepare my tea. But she has a strong objective in life, she just wants to be able to walk around the floor and explore the living room.
We live in a small house and the living room is where we have our books and hobby stuff, and she could get hurt if she is free, or she could nibble on our books or pee on the carpet, and then my husband would kill me.
So although I prefer to see the mice having their fun time freely, I'm considering buying an exercise ball for her. one with 18cm in diameter could be a nice size, but I have to know if they are safe.
