          The value you receive goes well beyond the cat issue you have today. Because we truly educate our clients on how cats act and behave — and especially how their behavior is totally different from the dogs that most people unconsciously use as models — our clients are able to more knowledgeably raise and enjoy cats for as long as they have cats.  Mieshelle’s most recent study of animal behavior was at Harvard University and she has written the first scholary-cited cat behavior book for cat owners that has been published in 4 languages

          It’s important to work with an experienced and certified cat behaviorist, but most importantly, one with formal study in animal behavior and a track record of proven results. The benefits of working with a cat behaviorist who really understands the latest in feline behavior can literally last you for years. (Like driving lessons, typing lessons, or a parenting class). A consultation with Mieshelle is nothing less than an investment towards a happier and problem-free cat — and toward your sanity. The advice, knowledge, and tools you’ll get during and after your consultation, as well as the traps (and products) to avoid, will repay you many times over.

          Zoologist testimonial:  “The reason people are so mesmerized by house cats is because they are truly miniature versions of lions, tigers, and leopards. Mieshelle explains in an unprecedented and a most accessible way, the behavior of the house cat, with her unique insight into the often misunderstood companion animal that is as wild as we have become civilized.” Dr. Jordan Carlton Schaul, PhD — Contributing Editor, National Geographic Society and Curator, Orange County Zoo
