If you've ever wondered, "Wow. Why is this thing so freaking weird?" while in the presence of a cat before, you're not alone. From thinking they're gods to wondering if cats are actually really aliens or are trying to take over the world, people have come up with all sorts of theories to try and justify their weird behaviors. This Ted-Ed lesson narrated by Tony Buffington will put many of those to rest with these clear explanations of some of the things felines do that leave you asking, "why are you like that, cat?" They still might be aliens, though.
Apparently, cats prefer a clean litter box because when it is odorless, it won't give away their location to predators.
They also like to explore small areas, because that's where small prey like mice would likely be hiding.
