Bad news: Cats even more manipulative than thought

They don’t talk, but when cats are upset about a change in their environment they let you know by acting sick – refusing to eat and vomiting excessively, even if they’re healthy, a new study finds.

“For veterinary clinicians, when you have a cat that’s not eating, is not using the litter box or has stuff coming up out of its mouth, the quality of the environment is another cause that needs to be addressed in coming up with a diagnosis,” said study researcher Tony Buffington, a professor of veterinary clinical sciences at Ohio State University.
