Okay so my dear darling problem child Ruby just HAS to pee on me during playtime. I take them out of their cage (mansion) and into the bathroom (our play area) and sit on the floor with them. Ruby always comes over, sits on my hand or arm and pees a little. Then 3 minuets later she comes back and does it again. Then 3 minutes later, again. Usually 3 or 4 times. EVERY TIME. Is this...normal...? And can I (should I) discourage it? How? In case you weren't sure, I don't love getting peed on. Oh, and my other rat (my sweet baby Opal) either waits until she goes back in her cage or will just go in a corner on the floor. Which is fine.
