Microchip compatible?


I live in Singapore and I'm thinking of ordering this product for my rabbit.I wanted to know if it will be able to recognize my rabbit's microchip ?

  • Non-Executive Director

It depends on the type of chip used, but virtually all microchips used worldwide these days are compatible. On the Sureflap website there is a compatability checker where you type in your microchip and the website can work out from that if it is going to work. There is a link to the page where you can do this here

Collar queiry


Do the cats have to use a collar in order to use this?

  • Non-Executive Director

No they do not need to have a collar. They must be microchipped and then you can easily program the cat flap to recognise the cat with that microchip. Microchips are tiny and are injected under the skin in the scruff of the neck - usually by a vet.

Two cat compatable


I have two cats so want to check I can programme both of their microchips into the catflap
My Yorkshire terrier puppy managed to get through my existing normal cat flap last night (I was outside thankfully and managed to intercept him ) so it's important only my 2 cats can use the catflap

  • Non-Executive Director

You can teach your flap to work with up to 32 different pets, so your two cats will be fine.

Other cats microchip


We have a neighbours cat who enters our catflap, is the microchip number manually entered? Is there the possibility of him being able to access ours if he is microchipped?

  • Non-Executive Director

You can set the flap to learn your own cat's microchip. Any cats with different chips will not be allowed through the flap. The instructions provided will explain how to do this and indeed your situation is exactly the sort of circumstance the Sureflap is intended to help with.

Can you use a microchip collar with these flaps

  • PHP Developer

The SureFlap Microchip Cat Flap is compatible with all the following types of microchip commonly used for pets, you would need to check that the chip number in the collar relates to one of the following:

  • 15-digit microchips (also known as FDXB)
  • 10-digit microchips (also known as FDXA) except those with codes starting 000..., 010...,or 020...
  • 9-digit microchips
