Cat Mate 234W White Lockable Cat Flap – Self-Lining up to 50mm

The Cat Mate 234W White Lockable Cat Flap is a simple, reliable cat door designed for everyday use in timber doors, uPVC door panels and other suitable panels. Its built-in self-lining tunnel fits installations up to 50mm (2") thick, creating a clean finished opening without requiring a separate tunnel liner.

With its white frame, transparent flap and straightforward 2-way locking control, the Cat Mate 234W is an excellent choice if you want a traditional cat flap without batteries, electronics, collar keys or complicated programming.

Self-Lining Cat Flap for Doors up to 50mm Thick

One of the main advantages of the Cat Mate 234W is its integral self-lining design. The tunnel section lines the cut edge of the door or panel, producing a much neater finished installation.

The self-lining section can accommodate installations up to approximately 50mm (2 inches) thick, making the 234W suitable for many common domestic door and panel applications.

Suitable for Timber & uPVC Door Panels

The Cat Mate 234W can be installed into a variety of suitable doors and panels, including:

• Timber doors
• uPVC door panels
• PVC panels
• Composite-style flat panels where suitable
• Thin panels
• Lightweight doors and panels

Please note: Before cutting a uPVC or other manufactured door, check its construction and ensure the proposed location is suitable for a cat flap.

Simple 2-Way Locking Control

The Cat Mate 234W keeps operation deliberately simple. A manual slide control lets you select between:

• Open – Your cat can enter and leave freely.
• Locked – Prevents your cat from entering or leaving through the flap.

There are no batteries to replace, no electronics to programme and no collar keys for your cat to wear.

Ideal as a Straightforward Everyday Cat Flap

Not every household needs a microchip or electronic cat flap. If you simply want to give your cat independent access while retaining the ability to lock the flap when required, the Cat Mate 234W provides a practical and economical solution.

Its uncomplicated design also makes it a good replacement option for older manual cat flaps where a similar-sized opening already exists.

Transparent Flap

The transparent door allows your cat to see through the flap before entering or leaving. This can be particularly useful when introducing a nervous cat or kitten to a cat flap for the first time.

The lightweight flap is designed for easy everyday operation while the durable frame can be wiped clean as required.

Training Your Cat to Use the Cat Flap

If your cat has never used a cat flap before, give them time to become comfortable with it. Initially holding the flap open can help your cat understand that the opening provides a safe route through the door.

Never force a nervous cat through the flap. Using treats, food and plenty of encouragement usually helps them learn quickly.
