Give your cat the freedom to come and go while keeping your home secure with this clever lockable cat door! The 2-way locking system lets you choose between fully locked, entry only, exit only, or completely free access - perfect for keeping kitty inside at night or when you're away. Designed for thin doors and screens up to 1/2-inch thick, making installation straightforward for most interior doors or screen doors. The polycarbonate flap is durable yet flexible, with silent action that won't wake you up with loud flapping sounds. The brush strip around the edges does double duty - reducing energy loss by sealing out drafts while also helping to keep out insects and debris. There's even an exterior rain seal included for additional weather protection if you're installing in an exterior door. The brown color blends nicely with most door finishes without standing out too much. What's really convenient is how this gives your cat independence while you maintain control over their comings and goings. No more getting up to let them in and out constantly! The quality construction means it'll handle years of daily use from even the most energetic felines. It's one of those pet products that actually makes life easier for both you and your cat once it's installed.
