1. Intelligent Door Gap Control Design The silicone pad is inserted into the 1–2 cm door gap to create a passage exclusively for pets, preventing the door from fully closing and avoiding air leaks. The ABS bracket is sturdy and impactresistant, remaining immovable even when cats or dogs bump against it. This balances the needs of both humans and pets. 2. No Installation or Removal Required, Just Hang and Use Instantly The elastic strap fits 99% of all interior doors and can be hung on the door in 3 seconds without drilling holes. The temporary door lock can be easily removed by peeling it off, leaving no damage to the door frame or wall. It's ideal for rental homes/furnished properties, offering worry convenience. 3. ABS Silicone, Durable and Soft, pinchproof claws made of foodgrade silicone; the ABS frame is dropproof and biteresistant (tested for 10 kg dogs). The smooth arc edges are burr, making it suitable for families with children and ensuring longterm use. 4. Passage for Multiple Scenarios Ideal for cat litter areas, pet feeding zones, balconies, etc., maintaining airflow while preventing pets from being trapped. The scientifically designed door width allows small dogs/kittens/senior pets to pass through easily without the risk of getting stuck.
