How long until I start worrying?

:( Maybe it's something else? I'm not sure why she would die so quickly unless the room are super dry with absolutely no warm spots?

I was gonna suggest checking craigslist juuuust in case she made it outside, but I doubt she went that far. I'm sorry :(

Its actually 50% humidity with a few warmer spots. It smells exactly like when I left a rat out too long and it started decomposing.
