“Zazie Todd has created a must-have guide to improving your cat’s life.”

Purr is cat-centered, so much that it feels like a very smart cat wrote it! Starting with the most recent scientific findings, Zazie Todd explains with clarity what cats enjoy, what is good for their well-being, and how we can build a strong reciprocal bond with them. Indispensable reading.”

“Pet expert Zazie Todd’s new book, Purr: The Science of Making Your Cat Happy, is a delightful, informative—and much-needed—compendium on how to have a wonderful relationship with your favorite felines. Cat lovers learn the science behind cats’ petting preferences; the multiple meanings of purrs, chirrups, and meows; how to best satisfy the scratching and stalking desires for indoor cats; and even how to keep both cats and wildlife safe if your felines spend time outside. Zazie Todd, a companion animal psychologist, also provides a fun section on—wait for it—how to train your cat. Yes, you can! If you love cats, you’ll love Purr." 
Cat Warren, author of the NYT bestseller What the Dog Knows: Scent, Science, and the Amazing Ways Dogs Perceive the World

Ingrid Johnson, Certified Cat Behavior Consultant, Fundamentally Feline, Atlanta, Ga.
