PetSafe: Staywell pet doors for dogs and cats, with spare parts

PetSafe comes from Knoxville, Tennessee, and carries on the Staywell flap brand. Here you will find dog and cat flaps along with spare parts.

PetSafe: pet doors with Staywell experience

It all started in 1991, when Randy Boyd founded the Radio Fence Corporation. Just a year later it was renamed Radio Systems Corporation, and since 2024 it has traded as PetSafe Brands. The company is based in Knoxville in the US state of Tennessee. In 2005 it acquired Staywell, at the time the largest maker of pet doors in Europe. Alongside pet flaps with and without microchip, the range includes training and anti-bark collars, drinking fountains and cat litter boxes.

The focus is on Staywell flaps. For dogs there are sturdy models such as the 640 and 660 with an aluminium frame, plus the 740 and 755. Cats come and go through the Staywell 400 and 420 with a magnetic key, through flaps with a 4-way lock or through the PETPORTE Microchip. If a flap is scratched or torn after years of use, you simply swap it for a matching replacement flap. You will also find refill spray for anti-bark collars here.

Frequently asked questions

How do I find the right replacement flap?
By the model number of your door, for example 620, 640 or 660. It is usually printed on the frame or in the instructions. The replacement flap must match exactly this number.

How does a magnetic cat flap open?
Your cat wears a small magnetic key on its collar. When it reaches the flap, the magnet releases the lock, while other animals stay outside.

What size do I need for my dog?
Measure your dog's shoulder height and its widest point. The opening should be a little larger so that it can walk through comfortably without ducking.

PetSafe flaps by purpose

The PetSafe range is divided by animal and purpose. Doors for small to large dogs with a sturdy frame are grouped under PetSafe Dog Flap. Models with magnet, microchip or 4-way lock for your cat are in PetSafe Cat Flap. If a flap is worn or a part is missing, take a look at PetSafe Spare Parts, where you will find replacement flaps and accessories to suit your model number.
