Okay, I'm probably just being paranoid, but.. Hannah's been snoozing for several hours on my bed. She stirred around and decided to lie in her crate instead, which is completely normal. However, next thing I know, she's vomiting. I get up to check on her as she's vomiting a second time. There's no food in the vomit. It's clear/white in color, and it appears to be phlegm-like. Is this "normal"? I did catch her eating on something when she went out for her last potty break, but I wasn't able to see what it was.

..And she just vomited again as I was typing this. Could it just be that she simply has an upset tummy?
