Large microchip pet door
Difficult to fit and one of the locks came out of alignment within a month preventing the door from opening, so had to hacksaw it off to continue using it - wouldn't buy it again
Don't buy it
No reflection on Zooplus, but there's not enough space to write all I want to say! Batteries go frequently, you can't stop a cat going out - if they are ill or a kitten for example, and there's a slight delay when they come in which they don't like so mine (used to cat flaps) stand there for ages with it clicking away.. Don't buy it, there are much better ones on the market.
