Not all only some more aggressive and territorial
Yes
If they are not fixed they will.
If your female cat is fixed aund another male cat is not fixed your female cat should not be attracted to the male cat but the male cat could be attracted to your female cat. ;)
Females spray in exactly the same way, although not as often. Female cats who are in heat are likely to spray a lot more when no in heat, to advertise herself to a male cat.
If it sprayed before it was fixed, it is possible it will spray after wards, but the incidents will be less frequent and should eventually stop. If it never learned to spray before it was fixed, it won't spray - the urge won't be there and it won't know how to do it.
I thought only male cats spray... never heard of a female cat do it! in fact they don't. I think your dreaming!
Yes. Spraying is a way of marking territory, and both male and female cats are very territorial. Except when a female is in heat, a male cat considers her no more than another intruder on his hunting grounds, and will spray to mark his turf.
Spray them with water.
Yes if they are not fixed. Male or female, if you let them they will escape and before you know it you'll have kittens.
Usually no because the fixed females no long produce the hormone sent that attract males
Male cats spray as they are more territorial than uneutured male cats. Also I think it may have something to do with attracting a mate. However, some neutered males will still spray if neutered later in life, mainly because it is now "habit". You might need to teach the cat that spraying is not acceptable.
A female cat, just like a male cat, can and will spray when on heat, or feel their territory is being threatened. They spray very strong-smelling urine to communicate with other cats in the area.
A male kitten typically does not start spraying, it sprays at all, until 6 months of age. A kitten neutered before it starts to spray is less likely to do so.
