Query: DO NOT BUY THIS!!!

I bought the Playcity kit to attach it to my Hartz cage. The connectors are horrible! My hamster managed to escape 6 times because the pieces just fell off. This accessory pack did nothing but cause me serious concern for my hamster because she would be missing for 3 days at a time and not to mention, we have a cat who would love to have her for dinner.I called the company to complain about their product and they told me I must have gotten a faulty kit and offered to send me a replacement for free. I highly doubt that it was "faulty". It's cheaply made and a waste of money.Save yourself some trouble and some money by going with Habitrail brand cages. They're connecters are lockable and it's not going to fall apart. I wish I would have bought it in the first place.
