My recuse kitties loves it. Both are from shelters and I didn't feel comfortable letting them outside. But my belief is all pets needs fresh air. And this was just perfect. I have a kitty door and hooked the outdoor play pen up to the door allowing them to go in and out as they pleased. This play pen makes me feel safe allowing them to go outside. And makes me happy knowing they are getting fresh air. This is a great idea for all pet owners who want their baby to be able to get fresh air. In time I plan on buying more kittywalks to give them more room to run. LOVE IT!
