ELI5: Why do animals "bite" at the sky when they have rabies ?

it causes the muscles of the throat to spasm uncontrollably, especially if the animal tries to swallow, eat, or drink. the spasms are very painful, and it often looks like "biting". The animal cannot eat or drink without triggering the spasms, or even swallow their own saliva, so they drool and foam at the mouth.
