Josey is kind of a wimp too, she is scared of new toys and it takes her a while to play with them, she is not too keen on strangers either, she only goes to me and sometimes my hubby.
I do take her out in her carrier from time to time, she goes along when we go visit my son and his family, that is a four hour drive one way, she plays and talks along the way and is good while we are there.
There is a step stool that I keep in the kitchen that I occasionally have to use to get something off the top shelves and every time I bring that thing out she growls, something about it scares her but I tell her its ok and she stops.
