Do cats actually eat your deceased body?

Hypothetically: Let’s say you died, all alone in your house. Would your cat eat the body?

It’s an outstanding question that keeps many pet owners awake at night, and one that’s rapidly gaining attention thanks to a recent study from the Forensic Investigation Research Station at Colorado Mesa University.

While conducting a study on body decomposition, forensic researchers accidentally stumbled upon their own footage of two feral felines chowing down on human corpses. Interestingly, the cats picked favourites, each coming back to their favoured body multiple times over several weeks.

“We have this kind of morbid curiosity about what our cats might do to us given the opportunity,” says Dr. Mikel Delgado, a cat behavior specialist at UC Davis who was not involved in the research. “Would they kill us? Would they snack on our dead body? And I think that’s why people kind of latched onto this particular research, is that it’s morbidly fascinating.”



Now to be clear, this study doesn’t mean that all cats will eat corpses, or even that most cats will. For one, the cats in this study were feral, and possibly hungry. While there’s no genetic difference between feral cats and domestic cats, Delgado believes it’s much less likely that a well-fed house-cat would engage in this behaviour.

For ethical reasons, information about this kind of thing tends to come from unintentional observations like the Colorado Mesa University one, rather than experiments in which scientists let house-cats loose on the recently departed.

(Can you imagine that research proposal?) But the study does provide some interesting insight into cat behaviour. “As a cat behaviourist, I think what’s really interesting about this study in particular is that we primarily think of cats as predators—as animals who hunt, kill, and then eat what they’ve killed,” Delgado says. “And in this case, it really highlights the fact that they are also scavengers.”

The body farm discovery sent Dr. Delgado down a rabbit hole of research into the phenomenon of cats eating dead bodies, which she documented on her blog. She found dozens of cases of domestic cats (and dogs) who had feasted on their deceased owners—most of the incidents were recorded in police reports.

But Delgado cautioned that this isn’t something that most people need to worry about. The cases are most common among pet owners who have a chronic illness that causes a sudden death, have free-roaming pets, and who are socially isolated, meaning that another person wouldn’t find them first in the event of their untimely demise.

“So there’s no reason for people to panic about an epidemic of pets eating people,” she says. “And the other thing that’s important to recognise is that just because animals will eat part of a corpse does not mean that they will eat you when you’re alive.”
