Boop has developed the chills.

Doesn't this mean pain? She just drank a ton of water, but doesn't want anything to do with going outside. She vomited up her supper from last night (she ate before having her bloody poop) sometime during the middle of the night. I thought I was keeping a closer watch on her.
Does anyone think it could be the Blue Buffalo? She is at the bottom of a bag, and it has taken some time to do that. Her kind wasn't on the recall list.
