This baby gate covers openings from 29.5 to 43 inches wide at a 30-inch height and adds a built-in pet door, 7.48 inches wide with an opening up to 7.09 inches tall, so cats can pass freely while the main gate keeps toddlers and dogs separated. The steel frame spaces its bars 2.2 inches apart and includes a dual-lock system that helps keep toddlers and pets from working the gate open on their own. It supports two installation methods, pressure-mounted for a damage-free setup or wall-mounted with hardware for a more permanent, secure fit, so it can go up in just a few minutes either way. One-hand operation means a parent can open and close the gate while holding a child or carrying items, and smooth, rounded edges cut down on scratches during daily use. The black finish and steel build are meant to hold up to repeated opening and closing at stairs, kitchens, hallways, and other doorways around the house.
