Review: Excellent cat flap - A good value for money microchip cat flap. I have two cats attached and it works perfectly for them. Easy to install in a solid door and quiet when working.
Review: Best purchase this year - I bought this cat flap as the local unneutered tom was coming through the normal cat flap and terrorising my cat, eating his food and then spraying urine everywhere to mark his territory. He even sprayed up the radio and also at the back of my hob. That was the final straw so I went on line and found this cat flap and I can honestly say it is brilliant! It's easy to install and it takes a couple of seconds for it to read your cat's microchip. I have no more worries about another cat coming in now and my cat is a lot more chilled. It does seem a little pricey but it really is worth it for the peace of mind and not having to get up every morning and start looking and sniffing for cat urine!!!

### ⭐⭐⭐⭐⭐ Excellent cat flap

### ⭐⭐⭐⭐⭐ Best purchase this year
*by L***N on 11 May 2012*

### ⭐⭐⭐⭐ Work great but could be cheaper
*by G***3 on 30 November 2015*

I bit expensive for what they are, but they do the job well. They fit together snugly to create a nice tidy tunnel. The cats love it and it's easy to keep clean. I'm only giving them four stars because 7 quid each is pretty dear for a piece of plastic!
