Thanks, PIF! That'll be a huge help! Izzy had definitely decided last night that she was ready to explore, so she'd gotten a few minutes out of the bathroom, but not very long at all. It did take her some time to get used to being in the bathroom, and her hiding place of choice (behind the toilet) left me calling her "potty kitty" all day yesterday.

Every time I've been in to check on her today, she's been curled up in the kitty bed, but she gets up when I come in there. Whenever I come out of the bathroom, however, Zelda won't let me touch her for about 5-10 minutes. After that, we're ok again.

I've started swapping out toys so that they can get used to each other's scents that way. And I figure we'll try for letting Izzy wander again in a couple of days. Especially if Zelda starts showing some interest in her through the door.
