Help! Fearful behaviour in Cats

[Catherine]

Is it the door she has a problem with? She seems better once you get her inside. Did something happen with the door when she tried to go in once. You know how cats never forget something that upsets them.

Maybe another cat came near her door.

Maybe she is just being weird, which is actually somewhat normal for a cat. Is there anywhere else she can go inside?

As it is you are having to spend more time than usual going back and forth. Could you take her home. Maybe this time she would stay.
