WATCH: Unlike dogs, cats do not have to look amused to get adopted

Researchers have found that cats' facial expressions don't impact their chances of getting adopted.

The researchers were curious about feline facial expressions and how they impacted dogs' chances of finding a home.

Shelter dogs which raise their eyebrows more were much more likely to get adopted.

This led the researchers to wanting to see if the same held true for shelter cats - and according to their study, published in Applied Animal Behaviour, it didn't. Using a system to track every possible facial expression for a cat, the researchers found the more facially expressive cats didn't do any better when it came to adoption .

Instead what seemed to work for cats was rubbing up against things. Those that spent their time rubbing toys and other objects had a 30% higher adoption rate.

The researchers believe that dogs evolved to raise their brows in order to better appeal to humans over their millenia-long domestication. Cats simply did not have the same pressure on them.
