I bought the same door and it is the bomb. I wanted it so I get to sleep in if 7:30 with all the indoor pets waking me up is sleeping in;> But at least I don't have to jump up;> And at night becuse I get home after dark through the winter months and I was afraid of preditors getting my girls. Now they are safe and I still say good night and do a head count. I have electric in the sleep coop so I have had no problems. You can see my set up on my page. You will love it. Good luck.
