I have almost the same issue, though I have adopted both a kitten and an
older cat both within the last two months.  The kitten (Sweet Pea) climbs
all over the cat (Max), chases his tail around the house, and basically
pesters the  hell out of him.  He hisses and growls and runs away most of
the time, but has finally started rolling over on his back and playing a
little.  I figure Max gets exercise by running away from her, so it's a good
thing :-)

How long have you had the kitten?  If your kitties are eating and sleeping
together, that's a good sign!  They'll work it out.  Your Max won't settle
down just because you get him fixed.  He will probably settle down a bit
when he grows out of kittenhood, though.

I actually find it kinda funny, my huge male cat running away from my dainty
little female kitten :-)  The dog just watches most of the time.

 Well, yes, within ten years or so!

 It is usually just a matter of time.  As you can see from my sig,
Minke is just a kitten, and Nanki Poo is nine years older.  It took
months for Nanki Poo to really accept Minke.

IThink Max will most likely calm down when he gets a bit older rather than
after
he's been *fixed*this has happened to me but my older cat was sixteen so she
found
it a little harder and I would never have bought the little one had I known
but my son
had just lost his, which he had found abandoned with two siblings who didn't
make it.
she was about four when she got out of the window and got run over so I got
the kitty for him
as he was living at my home for a while good luck, try to keep Max out of
Leo's way
as much as possiblefor now.  jp

I think you'll find Max will only calm down when he's no longer a
kitten :-)

Fixing him will also make a difference in his behaviour, but not
always that significant - with most of my male cats I've had fixed
they hardly changed at all.

It sounds like you're off to a pretty good start if Leo and Max are
doing these things together already...and I'm sure Max will learn the
hard way if he continues to pester Leo - but he'll learn quick.

Thank you all for your replies; I feel a bit better now that he'll greow out
of it some, and hopefully when he's old enough to get outside he can use up
some of his remaining energy and stop burrowing into the pillows of my
settee.

Yeah, right... :-))
