Thank you for the reply, Barncat.
My wife & I have been talking it over & we have decided to try keeping Brutus is the spare bedroom. It has two windows & we are going to come up with some kind of a screen door. In my own personal opinion, this MIGHT give him what he's wanted all along-privacy.
We both feel bad because even though we knew he wasn't tolerant of new katz, we just kept bringing them in.
EVERYTHING you said fits.
Our house is quite small, about the size of a double wide trailer.
11 katz. That's alot of territorial furbabies in a small space.
We will try to get this "segregation" instituted this weekend.
Thanks for the advice & good wishes.
