Pets are often adorable companions who brighten up our days – but as these owners discovered, they can also wreak havoc around the house.
From destroying objects to stealing food, these fun snaps show some animals’ naughtiest antics.
In a gallery of WackoJackoPhotos show pets next to handwritten notes their owners around the world have created to shame their beloved animals for their mischievous behavior.
For example, a cheeky dachshund waited until his owner had left the room to devour an entire family pizza.
Elsewhere, another greedy animal – believed to be based in the UK – ate its owner’s passport – just before the woman went on holiday.
Greedy! This naughty dog waited until his owner was out of the room and then demolished an entire family-sized pizza by himself.
Meanwhile, a feline knocked over his family’s pet fish and enjoyed it for dinner, while another cat apparently placed a “half-dead” mouse in its owner’s mouth because ” She didn’t wake up to look at her.”
One person also shamed their dog after the animal ruined their new screen door just three hours after it was completed.
