Review: Cat flap extension piece - Handy extension piece for Cat Mate cat flap. For use when you are putting the cat flap in a wall.
Review: Needed for wall installation of Cat Mate flap - The liner exactly fits with the cat flap as long as you buy the same make and seems to be made of reasonably good plastic. Mine came with no instructions at all for a wall fitting and I resorted to YouTube to find how best to fit this. If you have a cavity wall you will probably need more than one liner and you may also need to cut the depth of the liner to fit - it has 3 grooves around the outside to give you a straight line and it is moderately easy to cut it with a hacksaw. The video clip showed the liner being attached to the cat flap and/or extra liners using tape around the outside which is sensible. However I also recommend using some clear or white waterproof sealant at least along the bottom part where the cats walk through as water may get through the join otherwise.

### ⭐⭐⭐⭐ Hole lot of good
*by A***. on 7 March 2016*

Bought these to go through a cavity was as was fitting a Cat Mate Elite Microchip cat flap They are not cheap BUT they work well and give a neat finish They click on to the original flap opening to make it longer (push fit) You need this specific extender for the Cat Mate Elite Microchip cat flap (specific shape) - they clip on to the flap you bought - they fit into the exterior cover part (seal with silicon once you are happy with the fit) I did look at making an alternative from slate or plywood but could not find a neat way to do this. Tip Before you insert the catflap and extensions run some duck tape round each joint (on the outside of each extension, you wont see it when fitted).
