Why do animals sometimes just stare at nothing?


Do they actually see/hear something or are they just being weird?

In: Biology

When an herbivore “stares at nothing”, they are typically watching a broad swathe of territory, attempting to register any motion within that field. When a carnivore stares, it is usually because motion has already occurred and they are attempting to isolate the source.

Some animals, such as cats, can hear in freqeuncies humans cant. So they may be listening in on a bug or rodent that you simply cannot hear.
