Not really....didn't know for sure. Prescribed anti-deressents
thinking it was, perhaps, something behavioral but did no good.

Happy (the sick one) and Nick get,
Science Diet Senior+7
and our young cat gets Science Diet Adult.

All of them get a few of the Science Diet d/t nuggets to keep their
teeth clean.

We will give them special treats from time to time but nothing over
the top. The vet says their weights are right on the money.  Nick the
feral cat has only been to the vet once-he just wouldn't put up with
being caught and put in a cage. So far he has never had a sick day in
his life.

With the exception of Happy's bald spots all of them have good clean
coats, healthy mouths and good clear eyes and are active and alert.

He has been doing this for about two months and is nine years old.

He lives with two other cats and none of them are ever allowed to run
free. The cats have their own nice warm south facing porch protected
by chicken wire where they can lay in the sun and watch the birds and
stuff. We live in the woods in an isolated rural situation.

The other two cats are Nick 15 years old who is feral. He has never
allowed us to touch him but he will sleep at the foot of our bed and
gets along well with the other cats and us otherwise. He is our only
mouser which is very important to us living as we do out here in the
woods-our place would be over-run with field mice without him.

Little Man is a young stray we brought in a little over a year ago who
seems to have adjusted well to our household. Affectionate and always
knocking things off the desk and tables to get our attention when he
wants something from us. Just a good sound all-around stray barn cat.

Happy we got from my niece when he was about 5 years old when she
could no longer keep him. He is a Siamese. He is a very people-centric
cat who has little interest in the other cats. He sleeps between us in
the bed. He is always the first to notice our leaving the house and
the only one sitting in the window waiting for our return when we come
driving up the driveway. It  could be the most beautiful warm day with
the other two cats sitting in the sun out on the porch but happy will
be right next to me on the desk as I work on office stuff. His humans
seem to mean everything to him.

I wish I could do something for him.... I'm thinking of bringing him
into the University Vet school to see what they might have to say. The
local vets are primarily large animal vets for the local farmers and
may not be up on cat behavior problems.
