Large Cat Flap Fitting
A larger cat needs enough usable passage space and an opening placed at a comfortable height.

Large Cat Flap Fitting — size the aperture while flap for larger pets, with specification, handling and safe installation requirements agreed, with the glass specification, dimensions and access route agreed.
We consider the manufacturer's clear-opening dimensions alongside the available panel or wall space. The outer frame size alone does not tell you whether the pet can pass through comfortably.
The detail that matters
Which measurements matter when selecting a larger flap?
Compare your cat's size with the product's usable opening and allow suitable clearance for an easy passage.

Can the existing small opening simply be enlarged?
The panel, glass or wall must be checked first; enlargement may require a replacement component rather than further cutting.
What should I include in this enquiry?
Send the exact flap model and photographs of the proposed position from both sides. Include the postcode, the pet size and details of the panel, glazing or wall through which the opening is planned.
