Hello,
I am new to this forum, but thought I'd give it a try.

I have a 2 1/2 year old male siamese mix that recently began climbing
into the window ledge and playing in the blinds of our bedroom at
around 4:00am everyday.  He meows a lot too while doing this, but it's
more the damage to the blinds, and the noise he creates that is
bothering us.

We've tried giving him an over abundance of attention throughout the
day, cat nip after dinner to tire him out later, and it's not working.
All of that was after trying water spray, and loud noises to scare him
out of the window.  He just keeps going back to the windows...like he's
possessed!  We don't want to lock him out of the room in fear that
he'll destroy the rest of the house (he has slept in our bed since he
was a kitten, and the female in our house sleeps in the bedroom too,
although she does nothing wrong at night)

So I was wondering if some Cayenne Pepper in a pouch or sachet type
thing placed on the window sill would work to keep him out of there?
Or is that going to trigger him to try and mark his territory somewhere
else?

Our concern is that he'll  start spraying else where out of anger or
something.

any help is greatly appreciated!

Thanks
