You have a lot to learn about cats. One of the main points is that although dogs have owners, cats have STAFF.

Hi All,

Thanks for all you help and advice. Got a magnetic flap and will aim to fit tonight.

Am concerned about the stength of the wall as it is only single skin and how much damage using an SDS and bolster will do in loosening the surrounding brickwork. Am I right in worrying? its a single skin wall that was rebuilt about 15 years ago on the end of our kitchen. The flap will need to installed with one edge approx 4" away from the door frame/wall edge.

If you do lots of chain-drilling as advised, it should be OK, as that will minimise the jarring. At worst you might need to make up a bit of mortar for repointing if a brick or two comes loose,

Trouble is that if the blade is big enought to penetrate the brick depth, then the cuts will extend way beyond the corners of the cat flap due to the big radius on the cutting disc (think about it). This technique is fine for larger openings, but won't work on a piddly one like a cat hole.

That said, iy still might be useful to cut even a shallow slot around the periphery of where the hole will be, to define nice straight edges.

Thanks for all the advice. Finished it last night and all working fine.... Used angle grinder to create a "slot" in the brickwork which allowed me to stitch drill in a straight line and then bolster chisel it out.

All that effort and the cat just sniffed at it and walked off! He'll get used to it I am sure.

Shove it through a few times, then He'll get the idea.
