- Quiet, easy access: The cat flap lets your cat or small dog enter and exit smoothly and silently, so pets don’t feel trapped and you don’t need to open or close the door for them. - Four access modes (slide switch): Select the mode you need — free entry and exit, full lock, only go out, or only enter — to control your pet’s movements and keep stray animals out. - Durable, low-maintenance construction: The inner flap is made of strong ABS plastic for long service life. It resists wear and is easy to clean. - Better sealing and insulation: Sealing strips plus magnetic alignment keep the flap closed when not in use, helping to reduce odors, block insects, minimize cold air infiltration in summer, and limit heat loss in winter. - Widely compatible: Designed for interior and exterior doors made of wood, PVC, metal, cladding, and glass. Also suitable for installation on windows, walls, and cat litter boxes. - Practical performance: Smooth operation and magnetic closure reduce noise and drafts while giving reliable, predictable access control. Typical use scenarios: 1) Exterior door installation: Fit the flap into a back door (wood, PVC, metal, or cladding) so your cat can go outdoors and return without you needing to open the door. 2) Interior room access: Install between rooms to let a pet move freely while keeping other areas closed off or secured with the lock modes. 3) Litter box or window/wall installation: Mount on a litter box enclosure or a window/wall panel to contain odors and allow discrete pet access.
