Cat Whisperer® Behavior Modification

Vet-Referred Cat Behaviorist
Veterinarian testimonial: “Over the course of many years, Mieshelle has developed and refined her unique ability to think like a cat. On numerous occasions I have witnessed the life-changing benefits Mieshelle’s techniques can bring to cats and their sometimes very frustrated owners.” Dr. James R. Schultz DVM
Mieshelle Nagelschneider ACCBC, creator of Cat Whisperer behavior modification services, is one of the world’s most renowned and sought-after cat behaviorists. She will be publishing the most complete and up-to-date cat behavior book ever, The Cat Whisperer, with Random House Publishing while a major production company is currently pitching a feline equivalent of “The Dog Whisperer” to the networks. She recently finished filming a cat behavior episode for Animal Planet’s, Must Love Cats.
In four decades of living with cats, training them, studying them, treating them as a veterinary assistant, listening to them (even more valuable than whispering at them) and of course consulting on their unwanted behaviors, Mieshelle has logged more hours helping more cat owners solve more behavior issues than any other cat behaviorist in the world — including veterinary behaviorists. Her testimonials (more testimonials) are also easily unrivaled since 1999.
She is sought out, hired, and referred by veterinarians around the U.S., cat shelters, and wild-cat sanctuaries. When Hammacher Schlemmer needed a cat expert to test and review over a half-dozen advanced litter-box technologies, they came to Mieshelle.
Mieshelle stays current on the latest in cat behavioral science through observational and controlled studies on cats and continued education, most recently at Harvard University, where she focused on animal cognition.
She has worked with thousands of cat owners and vets, and of those clients who follow her recommendations, including her proprietary C.A.T. Plan™, her Cat Whisperer success rate is close to 100%.
Mieshelle’s Cat Whisperer expertise has been sought out by and featured in Martha Stewart Radio, Cat Fancy Magazine, USA Today, This Wild Life, The Divine Cat,Real Simple Magazine, Salon.com, and The Daily Cat. She also has her own cat behavior column in Pets Magazine. See our Media Room for the latest.
Mieshelle is a popular resource for many cat-only veterinary practices nationwide, over 40 wild cat sanctuaries, and countless animal shelters needing expert advice on feline behavior. She is a “Guardian Angel” of Best Friend’s Animal Society for cats that need special physical or psychological support and has worked professionally with domestic, wild, and feral cats. She was one of the referred Feline Behavior Consultants for Animal Aid and The Cat Adoption Team of Oregon, a 350-cat no-kill shelter, and has long been a featured behavioral resource on The Oregon Humane Society’s website.
Mieshelle worked side-by-side with veterinarians for many years, and has spent 20 years working professionally with cats of all kinds — from domestic cats to large exotics of the tiger family. Mieshelle started her career as a veterinary technician and psychology major. “I have been caring for animals since I began to walk,” she says, though not in a whisper, “dogs, cats, horses, birds — and have cared for them professionally since 1989. Before long, I realized cat owners are under-served and I began to focus my work exclusively on cat care — which sometimes means care of their owners too. ”
She is an Associate with The International Association of Animal Behavior Consultants, the Association of Animal Behavior Professionals, and a long time member of the Animal Behavior Society. She has been asked to be an expert witness on cat behavior in court cases involving damages caused by felines.
Mieshelle lives in the Pacific Northwest with 12 other animals, including seven cats (Jasper Moo Foo, Rhapsody in Blue, Clawde, Barthelme, Lady Josephine, Farsi Noir, and Braumwell), the cats’ bird friend Pidgeoto, a Savannah Monitor, their dog-toy Piccolo (a Teacup Chihuahua), and the cats’ personal horse and beast of burden, a soulful Great Dane named Jazzy.
Oh, and Nagelschneider is her real name — it’s German for “nail clipper,” and we’re not making that up. She’s also known for her uncanny ability to trim cats’ nails without needing to restrain them.
Mieshelle’s breakthrough book for solving and even preventing all feline behavior problems, The Cat Whisperer (Random House Publishing), will soon be at a bookstore near you!
