Not Ranked. Helpful AND tactful post? : 0 Re: Do NOT ever use these for cavies either | | I'm glad that I never thought of putting mine in an exercise ball or wheel. I mean, just look at them, they don't look like the type of animals to run in/on one. I don't even like the thought of putting my rats in exercise balls, they would much rather run on the couch or bed, I even avoid putting my hamsters in them for the same reason. |
