The moment in the post above — Why does my cat do this — is one of those small everyday scenes that says a lot about life with cats.
Cats do a lot of things that look weirdly inexplicable, and the moment captured in the post above is firmly in that tradition. Most of the time, though, the strange behavior makes perfect sense once you remember that cats spend their lives running an internal threat-and-reward engine inherited from small wild predators.
A sudden zoomie session, an extended stare into an empty corner, an aggressive grooming attack on a leg you did not know was offensive — every one of these is part of how cats process their environment. Their senses are far sharper than ours; a sound or smell that a human cannot detect can absolutely trigger a full reaction.
If your cat ever does something so strange you start to wonder if they have lost it, take the long way around: look at lighting, smells, movement just outside the window, or anything new in the room. Nine times out of ten the mystery has a perfectly logical, very cat-shaped explanation.
