Quick Summary
The Cat Mate 303 is a wall liner accessory for Cat Mate cat flaps, made for models 234 and 235 only. Each section measures 50 mm, so it is used to extend the tunnel through thicker walls and build the required depth in small increments.
The pack contains 1 liner. If the wall thickness needs more than one section, the liners can be combined to suit the opening. The paintable surface also lets the finished tunnel be blended into the surrounding decor.

What to Compare Before Buying
- Compatibility: This liner is for Cat Mate models 234 and 235 only. Confirm the cat flap model before ordering.
- Wall thickness: Each section adds 50 mm, so compare the opening depth with the number of liners required.
- Pack quantity: The pack contains 1 section. Multi-section installs need enough packs for the full tunnel length.
- Finish: The paintable surface is useful if you want the tunnel to match the surrounding wall after installation.
Choosing the Correct Version
This accessory is only suitable for Cat Mate cat flaps in the 234 and 235 range. It is a 50 mm wall liner section rather than a complete tunnel kit, so the selected quantity matters if the wall is thicker than one section.
Before You Decide
Check the exact cat flap model first, then compare the wall thickness with the number of 50 mm sections you need. Also confirm that a pack of 1 is enough for your opening, or that you are happy to join multiple sections for a longer tunnel.
