Some pets outgrow a cat door but would rattle around in a dog door. The Maxi is built for exactly them: ragdolls, Maine Coons, cavoodles and every solid little dog in between. One 267 mm cut-out, two glazing options — Slim Line when the glass is single-glazed, Dual Glaze when you’ve got modern double glazing and want the thermal seal kept honest.
Buying tip: if your home was built or re-windowed in the last 15 years, it’s probably double-glazed — pick Dual Glaze. Black suits dark aluminium joinery beautifully.
