Frequently Asked Questions (FAQs)

1. Can you lock a cat flap?

Locking the cat flap Many cat flaps have a lock or, in the case of some SureFlap cat flaps, a curfew mode that enables the door to be set to lock and unlock at the same times each day. If you live on a busy road, it's a great idea to lock the cat flap during rush hour or overnight.

2. Should you lock cat flaps overnight?

Please note: A cat should never be locked out all night. Also, ensure that cats have access to shelter in the day time, either providing a kennel or access to a shed. Even simpler would be to put in a microchip cat flap which only lets cats in that have their chips programmed into the cat flap register.

3. How do you lock a cat's cat flap?

The product comes complete with a tamper-proof lock. Simply press and hold down on the centre of the lock to move left and right to lock and unlock.

4. Can you lock a microchip cat flap?

You can lock the Microchip Cat Flap Connect using the 4-way rotary manual lock or using the curfew mode which can only be implemented using the Sure Petcare app.
