Who uses batteries anymore when you could use magnets?
That's right! Magnets! Forget those pet doors that rely on batteries that constantly need replacement. This cat door uses magnets in a collar that activate the plastic flap of the cat door so that your cat may come and go as he pleases. The only maintenance required is the occasional cleaning of the magnets. With it being magnetically activated, this door keeps stray cats out and your cat safely going in and out. This is a pet door where you can literally install it and forget it since the magnets last for a lifetime, and so does our door.
