An 18 hour bug?

Last Wednesday was a regular day like any other. But then, at about 4:00, it started to go down hill. Etta started to get clingy and droopy eyed. Wouldn't touch a bite of dinner and laid listlessly on the couch. As soon as I got done eating I wanted to snuggle. We read a couple of books and then she conked out. Thankfully her fever broke by 10:30 the next morning and she was doing well enough to go to the circus Thursday afternoon.
