Barn owls are more common than most people realize. Areas known for existing activity will naturally stand a greater chance of attracting these birds. By installing an owl house in areas of low populations, you help increase the likelihood of attracting barn owls and are aiding their long term survival. As their natural territory decreases due to urbanization, a barn owl house offers usable space for them to raise their young and protects them against predators.

Most dogs and cats are too large and are not common prey. Barn owls have been reported to lift up to 5 pounds. They typically prey on rats, mice, gophers, and small rabbits because they are an easy catch. If your dog weighs less than 9 pounds, you should be more concerned with other larger birds of prey, coyotes, raccoons, bobcats, and mountain lions. It is best to keep your small pet indoors, in an eclosure, or on a short leash under your supervision.
