I just adopted a 1.5 yr old female cat who was tossed around to several
different homes all across the country. I've never had such a cat
before. She follows you around all over the house and never wants you
out of her sight. When I leave for work in the morning she cries at the
door "meeeeoooooooooooowwwwwwww" like crazy.

The cat got used to and is now on my schedule. At night time when I go
to sleep she has a habbit which I don't understand. Just like a baby
kitten would suckel it's mothers milk when nursing, this cat suckels on
my arm for about 5 minutes before going to sleep. She does this every
night and I can't get her to stop. She is very obedient otherwise
(stops doing something when I say "no" firmly, and comes running when
you call her name).

Any idea why she would be doing this?
