Having just fitted a new oak veneer door in our kitchen I didn't want to ruin it by re-instating the cat flap. My only other option is to core a hole through the masonry of our house - 9" solid brick - and fit the cat flap to that. I think I would need at least a 180 mm (7") dia hole - is that OK on its own or should I think about a lintel support above it? Thanks for any advice diymostthings
The hole is fine. But do catflaps work(available) at 9 inches ? Double flap ? Will a cat use it ? Mr. HandyAndy - Really
The hole wont require a lintel, but will require a big drill! A 9 inch thick solid wall indicates that it could be a Victorian house.
I have done exactly that because of double glazed patio doors. I cut it 9" square fitted a marine ply box through the wall, cat flap on the outside and architrave inside, works a treat. no lintel needed. you may just need to give moggie some encouragement to start with.
Maybe easier and cheaper to remove the bricks, cut the perps on a half brick using an angle grinder. I suppose the brickwork is flemish or garden wall bond. I.e 3 stretchers then a header face.
Hi HandyAndy - Well she will do anything for a bowl of Tuna. Thanks for the advice on the hole. diymostthings
Its a 1930's house - not sure when cavities came in. thanks for the advice about not needing a lintel. diymostthings
Yes I was going to line it with something - I've got a bit of yellow gas main plastic tube which might work. The hole is too big for standard soil pipe. Out cat will do anything for a bowl of tuna!
Yes I'm warming to the idea of cutting out a square - having seen the cost of a large diamond core bit! Don't know the bonding of the bricks but thats a bit academic for me as the hole has got to go in one very restricted place. Thanks for your thoughts. diymostthings
