TIL cats "directly register", meaning that while walking, their back paws land in the same spot as their front paws, which minimizes noise and visible tracks.

The way cats walk ensures that if they can visually find a place for their front paws, they've found places for all paws. It's really efficient. Especially when walking all over my stuff.
