    Window Cat Flap Fitting

    Cat flap fitting for double-glazed, triple-glazed and single-glazed windows. We supply a new toughened glass panel with the cat flap hole pre-cut, then professionally fit it into your existing window frame. A great option when doors aren't suitable.

    Why Choose a Window Cat Flap?

    If your doors aren't suitable, or you'd rather keep them cat-flap-free, a window installation is the perfect alternative. It's also ideal for renters — the original window pane can be stored and reinstated when you move out.

    • Works with double & triple glazing
    • Keeps your doors untouched

    Do I Need FENSA to Replace a Glass Unit With a Cat Flap? (UK Guide)

    FENSA certificates are for replacement windows and doors — not for swapping a sealed glass unit. Fitting a cat flap into a new toughened pane is classed as a repair and falls outside FENSA's remit. Here's exactly what FENSA's own website says, and what you actually need instead.

    Can You Put a Cat Flap in Double Glazing? Here's How It Works (UK)

    The short answer is yes — but not by cutting the glass you already have. Here's how cat flaps are fitted into double-glazed doors and windows the right way.

    Cat Behaviour

    Indoor Cat Enrichment: Stopping Boredom Without a Cat Flap

    Indoor cats need three things replaced: hunting, height and territory. Two 10-minute wand-toy sessions a day, a puzzle feeder instead of a bowl, and vertical space by a window will resolve most indoor behaviour problems — over-grooming, night zoomies, door-dashing and food guarding. Enrichment is a routine, not a shopping list, but a handful of items do most of the work.
