- 4-Way Locking System: Our cat flap features dual knob-style locks with four modes—open, locked, in-only (allowing entry but not exit), and out-only (allowing exit but not entry). This gives you complete control over your pets' movements, ensuring your home stays secure. - Noise Reduction Design: The interior cat doors are equipped with a brush strip that minimizes noise during entry and exit.
