## Questions & Answers

**Q: Is the cat door see through transparent like glass or opaque, my cat will not go through unless she can see what is behind the door**
A: It is very clear, transparent, like glass.  Not opaque (my old cat door was probably what you call opaque, like a haze or film over it;  this is definitely clear in comparison).

**Q: Will this work in an alluminum storm door? Our cat is 16 lbs will it accomodate his size?**
A: The unit may stick out depending how thick the aluminum door is. I have it in a inside wooden door at a thickness of  an inch and a half. It should work but it may not be flush on both sides. I would try though. As for the cat size, I've got 2.  20 / 21lb maine coons , they walk right through with no problem whatsoever. The only door I was able to find to accommodate large cats. Again, I would buy and try.  Scot

**Q: How big is the required hole in the door?**
A: Thanks so much for answering my question...

**Q: What are the exterior dimensions of this pet door.???**
A: 9"wide x 9.5" long. That's the frame exterior.  It works great! I have it on an inside door to my bedroom. I can lock them out when I want to sleep. Or let them come in for morning cuddle time.
