Why Install a Cat Door?

A cat door is a smart way to give your feline companion the independence to explore, sunbathe, or return home without relying on you to open the door. It helps reduce stress for both you and your cat — especially if they meow to go in and out multiple times a day!

Modern cat flap installations include features like microchip recognition and magnetic locks, adding security while ensuring only your cat has access to your home. Whether you have a curious kitten or a seasoned prowler, it’s a great long-term solution for flexibility and peace of mind.

What to Consider Before Installing a Cat Door

Not all cat doors — or homes — are the same. Before committing to installing a cat door, here are a few important things to think about:

Glass type and location: Double-glazed or toughened glass panels may require replacement with a suitable safety glass unit.
Your cat’s size and behaviour: Some cats are hesitant, while others love to roam. Choosing the right size and style (manual vs microchip) matters.
Access control: Microchip cat doors can be programmed to lock at night, or only allow certain pets in or out—ideal for households with multiple pets or indoor/outdoor restrictions.
