Cat owners, this Wordcam pet door gives your furry friend the freedom they want while keeping your home secure! The 4-way locking mechanism is brilliant: set it to in/out access, in-only, out-only, or fully locked depending on your needs. The medium size (8.85x7.87 inches outer, 6.1x5.9 inch opening) works perfectly for most cats and small dogs. Installation is straightforward with the included full-size cutting template - works on wood, PVC, or metal doors from 1/2 to 2 inches thick. The sturdy ABS plastic frame and acrylic flap are built to last, and the magnetic closure ensures it seals properly after each use. The brush seals provide weatherproofing to keep out drafts, bugs, and that lovely litter box smell. Perfect for interior doors to give access to litter boxes or feeding areas, or exterior doors for coming and going as they please. Your cat will love the independence, and you'll love not having to play doorman all day. The black color looks discreet on most doors, and the solid construction means it won't feel cheap or flimsy. Say goodbye to scratched doors and constant meowing to be let in/out - this pet door makes everyone happier!
