Mine just loved the play pen. But when I would move them to a crate it was like I was doing something terribly wrong, so back to the play pen they went with their pee pads. I also use the play pen for my females who are about to whelp. That also worksd great for that although I did have one female that would get in and out of this play pen by herself. I couldn't figure out how in the world she was doing it till I watched her one day when she didn't see me looking....Oh my she would jump up on the side of the pen then jump out on the floor, scared me so bad as I thought she was really going to get hurt so I put the play pen next to the couch and the doggie couch next to my couch so she could go in and out when ever she wanted and I didn't have to worry about her getting hurt........learn something new all the time.
