Facebook is diving into the age-old divide between "cat people" and "dog lovers" to determine whether they share some personality traits with their beloved pets.

The research was shared today in honor of International Cat Day and, while the results may be in line with what one would expect, there are also some surprises that show what unites cat and dog owners.

Using object recognition technology, Facebook looked at 160,000 U.S. pet owners who posted a photo of their cat, dog or even both animals.

Cat owners are more likely to be single and have fewer friends than dog owners, according to the study.

It may come as no surprise that cat owners are more fond of indoor activities, such as reading, watching television and movies, giving them more time to spend with their feline friends.

They're also much more expressive on Facebook, running the gamut from commiserating with Grumpy Cat to sharing feeling of being happy and loved.

Facebook also pinpointed a few traits shared by cat and dog owners.

When it comes to curling up at home for some entertainment, both cat and dog owners equally love "Seinfeld," "The Big Bang Theory," "The Great Gatsby," and "Frozen."

They may have strong feelings about being a "cat or dog person," but pet owners on both sides are more likely to be friends with each other than with people who don't have pets, proving that cute animals can unite us all.
