Oh h*ll add me to the list.

Tak, I remember when you brought Betty home last year you talked about
her personality and how personable she was and easy to get along with
and how quickly she came out of her shell and how laid back she was.
Weeeelllll, those are all things you look for in a cat to see if they
would take another cat being in their space.  And the general rule of
thumb is that it does work better with kittens than older cats because
the established cat, Betty, is the dominant cat and the kitten will be
the non-dominant one and won't challenge her until way after they have
become acquainted.  They may not become best of friends until the kitten
is closer to adulthood, but most young cats can't stand to see a kitten
playing without wanting to get involved themselves.  It is just too much
of a temptation.  And kittens will play with anything, thus drawing the
cat in whether they want to or not.

And the bonus, you get to have a kitten in the house.  You think having
Betty around in endearing and adoring and beautiful, just wait 'til you
try a kitten on for size.  Kitten fever will never mean the same thing
again.

My recommendation, for the record, is that you get a male kitten
(usually opposite sexes work best - so it is said anyway, I've got two
of the same sex (both male) and they are pretty much inseparable) that
is 3-5 months old.  And, please, Tak, the sooner the better.  You know
we aren't going to leave you alone about this until you do the bidding
of our masters.  Besides, this IS kitten season and if you delay too
long, it will be hard to find the perfect kitten to go with Betty.

Bridget - nope, my cats know no shame
