put kitty in separate bedroom or bathroom   make sure adequate water, food
and litter box

leave alone  use a quiet voice when you talk to it.  If in the bathroom
allow time to explore with out anyone around if possible   no introductions
to other cats until the fur ball calms down  all you will do is cause
territorial aggression or fear

remember how would you feel if someone dropped you off in a new place, new
smells, new people  it take a couple days

Yes. Give her her own separate living quarters for a little while. We are
lucky. I have a big house, and a new cat gets to stay downstairs with me in
my computer room. After a bit, they will explore the rest of the house.
Especially at night, when the other cats and you are asleep. She is afraid
because she knows she is in the others territory. She just needs her own
space, which she will adopt as her own "territory" for a while.......Even if
it's just a closet, it's still something she needs.

I've read that cats can get awfully scared when put into an unfamiliar
environment because the objects around them are not "marked" with their
own smell. A cat leaves feromone marks by "polishing" surfaces with
his/her cheek and whiskers (that's where special feromone-producing
cells are situated. The book recommends to place the newcomer in a quiet
room with plenty of water, food and a toilet and let him/her get
comfortable and "mark" the room with the feromones. After that the cat
can be allowed to explore the rest of the territory. Surely, while
he/she's doing it, the other pet should be kept at a good distance. In
extreme cases feromone sprays are recommended (I've never used or even
seen one but that's what the author, a French vet, says).

When ever we took in a kitten, they weren't afraid of the older cats--it was
usually vice versa. Now when we took in an older one (a year or older), they
had some time adjusting to the others.

Oh the poor the kitty.. He reminds me of a cat we had that we got. She had
been a homeless kitten about a 2months old and lurking around our house
probably hanging with the other cats we had. At the time. We had 2 other cats
and a small dog. The kitten we took in took shelter in a milk crate that was
upside down in the house some where and did not want to come out for about 3 -
5 days. the Milk crate was near my dads comp so they bonded quick. We put
food and water near her for her because we couldnt get her to come out and we
didnt to force her. but after about a week of getting use to us being around
and knowin she could trust us she came out and layed with us and everything.
I would say just give him time but make sure theres contact between the 2 of
you and let him know he can trust you. Maybe even bribe him with a lil treat.
Seeing as the milk crate in my house was right near the comp and thats where
our cat would stay at first and my dad was always on the comp and so werent
me and my sis, our cat got use to us. pretty quick and eventually just
decided to test the water.
