For the first week or so we lived in this house, a cat turned up regularly mewing at the back door.
We knew the previous owners had no pets, thought it was nothing to do with us and ignored it.
After talking to our neighbours, it turns out that the cat was beiong fed by the previous owners of our house and was turning up for it's dinner. (although it wasn't technically theirs, don't know who the owner was/is)
After a week or two it stopped coming. So where did it go? Has been bothering me that it could have had a sad ending.
