thanks for all the hints!

I think part of her problem is fear. I have been taking her out in the alleyway where I want her to do her toileting so I can take her elsewhere for her "fun" walk, but I think any walk at this point is terrifying for her. It doesn't help that I live in a very urban area with high traffic.

I'll try the every ten minute thing tomorrow when I'm home all day.

Thankfully she's good in a crate and she slept all night without any incidence. I've been feeding her in her crate and giving her treats when she goes in to make her realize the crate is her good place rather than a bad one. And most importantly, she's safe from the cat in the crate!

I have her with me at work right now, and she's great in that she's very quiet, but she sure is fearful of everyone, especially men. Plenty of socialization is required for this girl!
