There’s an old saying that “Dogs have owners and cats have staff,” and as their staff, we are sometimes unwittingly the subject of their almost (but not quite!) sadistic sense of humor.

Pooping outside the litter box, “marking” a favorite article of clothing, or napping in your freshly cleaned laundry (oh, did you just wash your darks? Good thing kitty has white fur!): animal accidents or practical jokes?

Illustrator H. Caldwell Tanner seems to have unearthed a collection of Cool Pranks 4 Cats, which may very well be the feline handbook for expertly “enriching” the lives of their human staff.

Rated from “Meowcenary” to “Calic’owned,” these pranks reveal what cats really mean when they leave a dead bird by the front door!

We’ve got you figured out, felines! (At least for now, anyway.)

What pranks have your cats played on you?
