1. Safe and thoughtful The transparent flap allows the pet to see through the cat flap. The cat flap with 4way locking gives you the freedom to maintain control, allowing you to set it as an entranceonly, exitonly, both entrance and exit, or fully locked. 2. Made of weatherproof ABS plastic, the surface is smooth and durable. It features a fixed groove with pressure tabs for a weatherproof brush strip, making it easy to attach. Even if the brush strip comes loose, it can be easily reinserted into the groove. This design significantly reduces noise, blocks raindrops, wind, and pests like mosquitoes. 3.
