Additional Information


Spare collar key & 'breakaway' collar


Can my small dog use this pet door?

While some pet owners report being able to get a small dog and a large cat to share a large cat door, we would not recommend it. This Petsafe Smartdoor can be shared between small dogs and cats, but it does not have an LCD display.

How do I get my cat to use the cat door?

Positive reinforcement training is one of the best ways to train your furry friend to use their brand new pet door and practice good behavior. Luckily for cat parents, you don't even need a dog trainer or a clicker to do it. Check out our full article on pet training methods to learn how to train your pet to use their pet door.

Does the magnetic collar have an adjustable range?

No, your cat has to get close to the door for the sensor to detect it.

How long is the collar key's battery life?

This is a magnetic key for your cat and dog collar, so pet owners do not need to worry about rechargeable batteries or buying new AA batteries.

Will this interfere with my cat shock collar? What about my static correction collar?

Your training collar should be fine. Since the collar key is magnetic, it will not interfere with any cat training collar or its shock function. The collar will not negatively affect your cat's behavior or well-being.

Will the magnetic collar key interfere with my in-ground cat fence?

No. Even if your pet barrier containment system or invisible fence uses a radio signal to establish a barrier range, the collar key will not prevent your electric collar from operating properly or affect the shock levels on your collar or the volume of your collar's beeps. If your receiver collar or remote control uses a beeping sound, an electric shock, or vibrates when your cat goes outside the barrier, the Ideal collar key will not prevent it from working. The same can be said for any electric shock collars or dog training collar (such as a bark collar) that you may be using.
