Hi Linda,
There are no guarantees that your cat won't get into a fight with the next doors cat. In fact i would say that some sort of confrontation is inevitable. However you are correct that saying a female cat would be better as this does lead to less confrontation. However you must make sure that you have her neutered straight away.
I live in an area with many cats, some living right next door and yes i do sometimes here fights, but cats will only get into a serious fight when it's a life and death situation, as they do not want to suffer any injuries. Most fights are therefore mainly warnings. Territory is normally shared out after a while and the confrontations will reduce. Don't worry too much; it is possible to have a cat even though your neighbour has a cat. :)
