We have tried a very large cage with a smaller cage inside of it, an attached cage, and a potty basket in the cage. Anything that seems to be a cage, she sees as off limits for pottying in! We will try this week to just leave her in and see how she responds. Last Friday, our pet sitter forgot to get her out. When I got home, she had not pooped in her cage but did not seem overly anxious to get out to poop.
