Why Cat Bites Matter

While cat bites look a lot smaller than dog bites, cat bites have certain features that make them more dangerous. Cats have thin sharp teeth that dig into skin and drive bacteria deep into the wound. This then causes the wound to potentially close up around the bacteria, which can lead to an infection.

There is a remarkable amount of research around cat bites. We’ve summarized the best studies we could find below to cover everything you wanted to know, or perhaps didn’t want to know, about cat bites.

Not surprising to most who have owned a cat(s), your author included, cat bites most often end up on the hands and arms.

One study in the New England Journal of Medicine estimated that 63% of cat bites were on the patients’ hands, followed by the arm with 23% of bites.

This data suggests that a lot of cat bites come when petting or interacting with cats. Relatively few bites occur on the leg (9%) suggesting that walking away from a frightened cat may be a good strategy.

If you do get a cat bite, you’ll likely find out pretty quickly if it’s going to get infected.

According to a study in the New England Journal of Medicine, the average patient with a cat bite first noticed their infections about 12 hours after the bite. Dog bites take about twice as long to set in.

For an infection to set in, bacteria need time to get “settled” and multiply in your body which is why there is a delay between a bite and any infection symptoms.
