This pet gate can protect and isolate pets. It will prevent your beloved pets, such as cats and dogs, from escaping outside or into dangerous places. When introducing a new furry friend to your family, it can play a very important role in providing isolation. The cat gate measures 90cm x 210cm, fitting door sizes of 90cm x 210cm. Please measure the size before purchasing, including the door frame. It is more resistant and durable than ordinary fiberglass and polyester and can withstand cat scratches under normal circumstances. GOOD VENTILATION - The gate allows air to circulate freely, so you can enjoy fresh air at all times and reduce the stifling heat in summer. At the same time, it also keeps out mosquitoes, flies, and other insects. EASY INSTALLATION - Simply attach the hook-and-loop fastener to the four sides of the cat gate, then peel off the white adhesive backing and stick the gate to the door frame without any tools. It is suitable for sliding doors, patio doors, balcony doors, front doors, greenhouse doors and so on.
