young kitten is easy to teach... its very hard to train the adult to behave.
neuter or spay will not change the number one characteristic - which is territory protection. even neutered female will smack down un-neutered female.
even if you spay the male, they will still hunt down other male.
that is the reason why you need to know the genetic. bad behavior genetic is very hard to maintain.
one of my female neutered cat never like other cats. the only cats she can be with is her own brother and the other 2 adult that she saw and be with when she grew up.
one of my male spayed cat is very good with other cat, but hate so much another male spayed cat. see, both of them are spayed and they still behave like slapping each other. they have been together in a house almost 1 year now. and believe it or not, i can never tell if they become BFF or not. seem like they don't like each other till death

lucky the other one, will surrender if things getting bad.
if one cat is a fighter, and other one is a surrender = then this will reduce fight.
if you have both fighter, then very hard lah eheheheh.. the never ending story.
anyway Fight to be hero is what animal do anyway. not even cat, even monkey will fight over territory.
my oldest cat which is 4 years old is a good boy. he never hiss at any cat. and another female mix persian age 2 years old behave very good. Proven that, persian breed will always produce good behavior. Please don't try this at home

after deep study about this fighting cats, i found out both the background comes from a fighter cat types.
if you happened want to breed this type of cats, better stop doing it. after research and study, i found out that in 1 litter, there will be genetic follower. it will be worst if both father and mother has behavior problem matters.
in cattery, breeder will neutered/spayed their breed cat in order to stop producing bad behavior cat which may lead to un-perfect show cat.
the best way are:
- get to know your cat

is he/she ever meet other cat? if NO - you better start introducing him/her to practice meeting other cats. don't jump to the conclusion of getting it now and bring it straight home.
- second, if you plan to adopt a cat from friends, try bring your cat to your friends house for first introduction. see how your cat works with other cat. beside you can see the background of that cat.
getting 2 or more cats together took a long time. i success in making some of my cat become BFF, some will never be like what i want it to be

but im stil lucky that in a fight there will always be white flag of surrender sign. so it stop instantly

so be patient, try to get younger cat better.
very hight percentage people successful making 2 or more cats become BFF.
small percentage fail, to make one.
so then, get to know your cat is a better way. if you know he/she is a type that do not like strangers... better don't try it a home, because you may have a new cat that feel like living in prison with gangster
