oh no! I don't really have a good answer for this, b/c Rorschach's startle reflex is ridic and it is never a problem to get him up for anything. Obviously force is a bad idea, as that'll just make it worse. Does she have a favourite toy? Or does she like squeaky toys maybe? Sometimes with Rory I try to pretend I'm having a great time without him - playing with a tennis ball on my own, squeaking a squeaker, eating delicious food, that kind of thing, to pique his curiosity. If feasible, you could sit outside her crate and do something that would interest her?

Other than that, I hope the nap thing works. My other advice would be to make sure that, when she comes out of her crate, you do fun indoor things with her for a while, so that she doesn't associate coming out of the crate with going out in the cold.
