Give Your Pets the Freedom They Deserve with a Pet, Cat or Dog Door When your pets have the choice whether to be out in the yard or in the house, they're less anxious and you'll have fewer messes to clean up when you get home. High quality pet doors are energy efficient, easy to use and safe for your pet. Soft, flexible flaps and strong security doors with pin locks create the perfect combination for your pet's freedom and your peace of mind. Because every home and pet situation is unique, it's important to know the many options available for installing your pet door. Your pet door can be installed through interior or exterior walls, doors or in screens and windows or in sliding glass patio doors and fixed glass of all kinds. Specializing in Pet Door Installation I have worked exclusively with Hale Pet Door for over 12 years, and collaborated with Bill Hale to write the instruction manual. Prior to that I was involved in various types of construction for over 10 years. I'm very happy knowing that when I leave a house, I just made life easier for some people and their pets.
