In the Disney cartoon “The Aristocats,” the cats sing a song about how everyone wants to live the carefree lifestyle of a cat. As one man in Idaho discovered, that even applies to black bears as well.
In this man’s condo, a black bear tried to squeeze its way through his cat door. While unsuccessful, it does show the danger of a cat door that can let in all sorts of animals besides your cat. If you have a cat door, it’s best to have a special collar on your cat so the cat door only opens for your cat and no other animals. Otherwise you could get a surprise and find other animals wandering around your house.
