We love cats for their adorable cute looks, like the internet celebrity Pusheen cat that decided to hide in a cardboard box as many cats do. It's a widely known fact that cats, same Pusheen, love boxes. For them, no toy in the world, no matter how expensive it is, can replace a cardboard box. There are a lot of reasons why all cats behave like Pusheen in a box here, and the main one is that it is an enclosed space and they feel safe there. As ambush predators, they are programmed to find confined spaces to hunt and hide there, and they feel kinda safe there. That's why snug cardboard boxes fit cats' needs perfectly, the same as a cute Pusheen cat here. A fanart Pusheen progress bar for YouTube with Pusheen in a Box.
