Apparently you can get a cat mask at any Halloween store or online, and it won't matter how realistic it looks if you want to freak out your pets.

You'd think since they live with other cats they wouldn't get so scared, but maybe the idea of a giant talking cat is what actually spooked them.

Toward the end of this short video you can hear one of the cats moaning or growling angrily in protest to his "new brother".

The guy recording the video had no idea his pets would get startled the way they did, but we are so happy he decided to record his first interaction with his many feline friends. Now the world can enjoy this bizarre reaction to an even more bizarre video.
