This way, you can also check the colour of your neighbour’s cat flap to change the colour of your cat’s key when both are the same.

How to put cat flaps in a small door?

A cat flap is a small opening in your door that allows your cat to come and go as it pleases without you having to worry about opening and closing the door constantly. Here’s how to put a cat flap in your door.

1. Choose where your cat is most comfortable and where the cat flap will be most convenient. 
2. Cut out the opening for the cat flap.
3. Carefully measure and cut out the hole for the cat flap with a jigsaw or a circular saw. 
4. Be sure to follow the instructions that come with the cat flap to ensure that the hole is the right size. 
5. Install the cat flap and secure it in place according to the instructions that come with the product. 
6. Most cat flaps come with a locking mechanism that allows you to control when the cat flap is open or closed. 
7. Be sure to secure the cat flap in place and add weather stripping to help prevent drafts.
8. Train your cat to use the cat flap.

Start by propping the cat flap open and letting your cat explore it on their own. In addition, when your cat is comfortable with the flap, please encourage them to use it by placing their favourite treats on the other side.

How does a microchip cat flap work?

A microchip cat flap is a pet product designed for cats and dogs that enables them to come and go as they please while also containing them within a certain area.

 It differs from a typical cat flap or dog door in that it is equipped with a microchip reader that allows only authorised pets to enter or exit through the flap. The microchip, implanted in the cat or dog’s body by a vet, is a small and grain-of-rice-sized radio-frequency identification RFID device containing an identification number unique to the pet.

This number is programmed into the cat flap’s locking mechanism, which is utilised to release the latch and allow access through the flap. When the pet approaches the cat flap, the scanner reads the implanted microchip and recognises the identification number. 

If the number matches the one programmed into the locking mechanism, the flap opens, enabling the pet to come in or go out. This system ensures that only pets with authorised microchips are granted access, preventing unwanted intruders or strays from entering the home. Some manufacturers of microchip cat flaps, such as SureFlap, offer a range of products that cater to various requirements and preferences. 

These include flap-opening options across walls, doors, and even double-glazed glass. There are also different sizes available to accommodate small cats, large cats, and small dogs. 

The microchip cat flap can also operate magnetically or through the use of collar tags. However, microchipping is the most secure and humane option since it eliminates the risks of collars and prevent accidents such as choking. 

Some high-tech pet brands like PetSafe, Endura, Staywell, and High Tech Pet, offer a weatherproof and sturdy design made from strong materials, including weather-stripping for extra insulation, liners for easy installation, and electromagnetic or radio-frequency locking mechanism for more precise pass-through access. 

Microchip cat flaps present enormous benefits to pet owners in terms of convenience, security, and safety. It’s a practical solution to enable cats and dogs to access their litter boxes or kennels, ultimately improving their quality of life while providing assurance to pet owners. 

Additionally, the technology is also useful for animal shelters that want to keep their animals safe and secure. Installing a microchip cat flap involves cutting out a panel on the door or window of the house and fitting it with a latch or hinge that operates the flap opening.
