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

First, let’s remember that cats are 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 cats love curling 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!
