They're meant to be affectionate, loyal faces in your home, but it seems nobody told this group of surly pets. This hilarious collection of the most sour-faced domestic animals shows just how evil pets can look when the mood strikes.
Among the gallery of sinister snaps is a frog sporting a particularly evil smile, cats pictured with typical disdain, and even puppies scowling at the camera.
The unique group of pictures even features a surly owl glaring at the camera while perched on top of a workbench.
Some of the pets appear aggrieved due to the situation they are pictured in, such as a cat wrapped in a piece of curtain material.
Others look unhappy at being made to complete car journeys with humans, or simply don't enjoy having their picture taken.
