Please read my profile before purchasing. Please understand before purchasing. I purchased this used, and it feels warped overall. I bought the slatted floor from Usagi no Shippo (Rabbit's Tail), but it was warped when I disassembled it. Also, the spring for the top door is missing. I think I have a Pro Cage. I apologize if I'm mistaken. My rabbit had no problems using it. I will clean it as much as possible before shipping. Rabbit Cage Usagi no Shippo (Rabbit's Tail)
