Is it OK to bring a new kitten?

I have one kitten, he is 6 months old. I was wondering if I bring another Kitten a bit younger, would they get along well? or they might create problems?

would my first kitten feel jealous? or the would play together when I am at work?

my first kitten is a boy, should I bring another boy, or it is better to bring a girl?

if One is boy and one is girl and they are both neutered, would they desire for the other sex? or they only wont have babies?

your advise would be very appreciated,

Thanks,

Katy

At that age kittens usually take to each other well.  The current kitten should be neutered before you bring another one in, sex matters less than personality.  You want a confident outgoing kitten but not one that's domineering.  I'd go and ask my local rescues for the right personality kitten.
