A pet photographer captures animals shaking their heads.
Carli Davidson is the photographer behind the pictures.
Her first two books were “Shake Dogs” and “Shake Puppies” - both of those were big hits.
Now she's coming out with a third book for cat lovers.
“Shake Cats” features 61 different cats, most of them from shelters.
Davidson got the idea while watching her own dog shake slobber from his mouth.
She uses ear drops to get the animals to shake their heads.
