This is new behavior. This cat loves food, in all forms. She stopped eating today and shows no interest at all in food. I can open up a can of wet food, her favorite, right in front of her and she won't even look at it.

She still has a little bit of spunk but she seems to be slowing down. She's sitting in odd locations: dark corners.

She's is a young cat, probably right out of adolescence.

She's been vomiting for two days but the first day did not seem strange because my cats sometimes go through a spell of vomiting for a day (hairball, probably). But now it's serious.
