Frequently Asked Questions (FAQs)

1. Is there an alternative to a cat flap?

The Most Secure Option One of the most unique and beneficial pros of choosing LockLatch™ as your cat door alternative, is its security. Traditional installed cat flaps can be either locked (keeping your home and valuables safe and secure) or unlocked (giving your pet free access as a cat flap is designed to do).

2. Can you fit a cat flap in a uPVC door?

You can fit a cat flap into solid uPVC doors fairly easily, since you can simply cut a hole in the door. Remember to check that your flap is large enough for your cat, and ensure the height is appropriate so that the cat does not have to jump.

3. Can burglars get through cat flaps?

Adding a cat flap to a door immediately weakens it but the greatest issue is it can allow burglars to reach in and hook things like keys out with a tool or even found object such as a garden cane.
