Hi Jack,

A female companion would be better, in my experience.  With two males, you
may find they fight each other for dominance.  This is fine if one cat
yields, but can otherwise be very difficult to handle.  Apart from the
fighting, inappropriate fouling often occurs as the cats indulge in
territorial marking.  You wouldn't like it.  Female cats were made for male
cats.

I have two female cats who get along, but even they have their disputes from
time to time.   Mostly, they're fighting over me because they haven't
learned to share me nicely yet :-)

However, since you're starting with a male cat, 2 females aren't an option
for you.  Whatever you choose, don't be taken in by the sociable, cute
kitten act.  A sociable, cute kitten quickly become a spitting green-eyed
monster when it discovers it's not No. One.

If you do get a new kitten, remember that you will now need two of
everything:  2 pet carriers, 2 litter trays, 2 food bowls, 2 toy
collections, 2 bank balances ...
you'll love it!

Hope all goes well.
