I have that playpen too the large one think the medium woulda been better had to get rid of one of my wardrobes to fit it in ooops. Its really good isn't it? My robo and syrian love it.
Kissa they are adorable! I adore how they are on the saucer. It's amazing how fast those little feet go! I also have the same playpen for Patches. I also use it for Yoda, my Chihuahua when we go to my sister's house. I have the medium one. They are great.
