​The SureFlap Microchip Flap

If you're looking for a door that will give you the absolute best security on the market then you'll want to go with a model from SureFlap. SureFlap also makes amazing feeders and other cool products, but their claim to fame is really in that they use your cat's microchip to grant access to their door.

If you don't yet have a microchip in your kitty then no worries, they send you one to attach to your cat's collar! And if your fur ball is going outside I always highly recommend a collar just in case!

Considering a cat tracker of some sort may be worthwhile too if your kitty disappears for long periods. But the key features of this door are:

  • Excellent security driven by your cat's microchip ID or the included collar tag, no strange animals
  • You can program your door to lock and unlock at specific times of day
  • The door dimensions are about 7" wide by about 6.75" tall, great for most cats
  • You can easily store multiple cats in the door memory, all cats can come and go
  • Features multiple locking modes for only letting certain cats in or locking it down completely
"Works great for our two indoor/outdoor cats. They can pop out whenever they want it and has so far stopped anything foreign from coming in."

It is very important to note the following before purchasing the SureFlap:

  • The door will always let any pet exit, you cannot lock down the door from the inside
  • Raccoons have been ​able to pry this model open from the outside

​The Kitty Pass Interior Cat Door

A few other things worth noting about this door:

It is worth noting the following before making a purchase:

  • If you've got kids in the house that may constantly lean against or pull on this then you may want to consider using screws to secure it instead of the included 3M tape
