All cat owners know that cats only have three modes: 1) doesn't care you exist, 2) purring cat cuddle time and 3) devil incarnate.
But animal experts know that the royal fur balls put up a really good poker face and, contrary to their apparent apathy toward life, our feline friends actually do feel pain. They just don't show it.
In an attempt to crack the mystery that is the household cat, two researchers from the University of Lincoln consulted with 19 veterinary scientists from around the world to figure out the subtle ways cats tell us they're hurting.
Their results were recently published in the scientific journal PLOS One, bringing all of humanity one step closer to finally understanding these totally lovable fur friends.
The researchers uncovered two signs that are "sufficient" for assessing a cat's pain, meaning their presence alone indicates that the cat is in pain.
For example, if you've noticed that Mr. Bigglesworth has stopped grooming himself -- an activity that typically occupies about half of an adult cat's day -- that could mean he's experiencing at least low levels of pain.
"Cats are notorious for not showing that they are in pain," Caroline Fawcett, chairman of Feline Friends, an organization that supported the research, said in a university press release. "And the more we can find out what the signals are, then the sooner we can get them to the vets for diagnosis and treatment."
So when your cat starts acting a little funny, don't brush it off as a weird quirk.
