Is your schedule planned around potty breaks. Let your four-legged friends come and go on their own time with the PetSafe Freedom aluminum dog and cat door. Designed to withstand wear and tear, the metal frame with its reinforced aluminum corners is great for active dogs and multi-pet households. The magnetic, tinted flap, weather stripping and a slide-in closing panel gives you protection against drafts and outdoor temperatures. You can also use the slide-in closing panel to control your pets access and keep stray animals out of your home. Installing this cat and doggie door is an easy DIY project that fits doors between 3/8 and 2 in thick. The flexible flap gives pets up to 220 lb easy access in and out.
