Cats love catnip. Whether it's eating it, playing with it, or rolling around in it, catnip turns our domestic feline friends into hilarious balls of activity. Carefree and unconstrained, they are free to be silly, exceptionally playful, and downright gnarly.

Professional pet photographer and self-confessed crazy cat man Andrew Marttila (the photographer behind Shop Cats of New York) captures a range of the cats' silly and expressive personalities as they react to their catnip trip. Delightful, elegant Fluffy transforms into a hell-bent renegade. Shy, reserved Mittens becomes a free-loving acrobat. In the blink of an eye, a cat's expression transforms from bored to inquisitive to playful to curious to bizarre . . . to utterly unhinged. A fun and delightful look at our furry companions, this gift book is perfect for every cat lover.
