I bought my plastic one (has diamond shapes in it) at petsmart for around 70-80 bucks but a few months after I bought it I was looking online at kmart (baby section) & it was the very same pen (no joke) that they had listed for babies only it was about 20-25 bucka cheaper-I was not happy!! also they have the extensions (2 extra panels) that you can buy only online at petsmart.com which I got & it has been really great, she's been in hers from day one & still lovin her little condo
