There's only one thing that cute cats love more than laying around and doing sweet nothing - and that's fitting into small places. They take even bigger pleasure in wrapping themselves in an Amazon box, a shoe shelf, or even a pizza box when they know that their human thinks they won't be able to fit - oh, the pleasure of proving your human slave wrong...

While a lot of us find this 'cat in a box' behavior bizarre (I mean, why would you put yourself in a place that looks painfully uncomfortable), scientists have a couple of explanations for these funny cat antics.

First, let's remember that our silly cats are actually fierce predators - and boxes are great places to stalk victims from and hide. Therefore, cats get a sense of comfort and security from enclosed spaces, and some research suggests that boxes even decrease feline stress levels.

Another reason why we often find sleeping cats curled up in small and tiny places is that it helps them preserve their body heat. The thermoneutral zone for a domestic cat is 86 to 97 degrees Fahrenheit, which happens to be 20 degrees higher than ours. Therefore, getting into a tiny box may serve as a smart heat-saving strategy.

Whatever the exact reasons, let's admit it - cats can be very hilarious! And if you don't believe us, check the funny cat photos below.
