We let the Pixelcat go outside when we lived on a quiet street and had a yard. Our apartment was very small and poorly ventilated, so having a catbox, no matter how often we cleaned it, didn't work out too well.

Then we moved to a bigger place on a busy street, and The Pix became an indoor-only cat. (Sorry, buddy!) He adjusted very well. We've since moved again to another place where it would be inappropriate to let him outdoors, but we have some great windows for him to look out of, so he's happy.

And the bunny always stays in, of course. She likes the carpet!
