Review: Excellent cat flap - I originally bought an alternative cat flap based on my boys sizes and weights, but having fitted it, it soon became obvious that it was far too small. I don't think my boys are excessively large, they are Siamese cross and weigh 6-6.5kg. I genuinely did not believe they would need a large cat flap - but I was wrong. This cat flap is excellent quality and fits beautifully in our wooden kitchen door. Absolutely no draught gets through, but it is still easy enough for the boys to push. The locking mechanism could perhaps be simpler, but once you suss out how it works, it's no big deal. It's a very solid, quality item. My boys are 3 years old and had never used a cat flap before, with the exception of the previous purchase that was too small. Having struggled with that one, I wondered if it would put them off trying with this one, but the initial hesitance lasted no more than a few hours before they realised they could get through this one so much easier. I admit, the original cat flap was cheaper, but you can't put a price on your cats happiness, and it's not as if this was overpriced, it is worth every penny. Definitely recommended. Review: Nice product - Good pet safety with easy to use mechanism, good pet access, we use for our pet Yorkie Jack, good quality construction and,seems to have good durability, a nice value for money product. ## Features - Warning:Not suitable for children under 3 years.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent cat flap *by K***S on 7 May 2025* I originally bought an alternative cat flap based on my boys sizes and weights, but having fitted it, it soon became obvious that it was far too small.
