This Kennel Kab for Cats is the perfect item for taking your cat to the vet or just about anywhere outside your home. The Kennel Kab is basically a pet carrier in the small size. It fits a cat easily, but could also be used for a very small dog, ferret, bunny, etc. It is made of nice durable plastic with lots of ventilation for your kitty. The front has cage type bars that open and close allowing to insert or remove your pet. The bars lock securely in place, so you don't have to worry about your cat escaping. I use mine every time I take one of my cats to the vet. I pop him in the Kab and he rides in the car nice and secure. I don't have to worry about him getting out by mistake or causing an accident by distracting me while I'm driving. When I go into the vet, I don't have to worry about the cat jumping out of my arms and getting away. He is safe and secure. I don't worry about other cats or dogs scaring him while at the vet either, they can't get to him and he can't get to them. As a pet owner, I wouldn't be without a carrier. They come in various sizes to meet your needs.
