flap » flat
Spotted in the wild:
- I have two cats and a third one that keeps getting into my house, do you know if there is a cat flat that I can get that electroncally lets my two cats in only ? (rec.pets, Jan 21, 1997)
- A tom cat has (on two nights in succession) entred my house through the cat flat and terrorized my 3 yr old female cat. (rec.pets.cats.health+behav, Oct 25, 1999)
- They have a cat flat and the 4 others came straight in as soon as they heard us. (pet-manual.co.uk forum)
I came across _cat flat_ for _cat flap_ in an ad offering to share a house in London. A large majority of the occurrences appear to be typos, though some might not be, and instead relate either to the flat shape of the object or the idea of accommodation specially devised for a cat (a _flat_ in BrE corresponding to an _apartment_ in AmE).
