The Cat Behaviorist and Doctor Go Beyond the Obvious Feline Behavior Strategies and Facts During Behavior Consultations

Professional Statement

Founder of the “Cat Behaviorist” specialty and the first cat-only behavior clinic in the United States, Mieshelle Nagelschneider has always felt that it’s important to offer support to cats and their owners, which has led her to her career as a behaviorist for cats.  It allows her to help cats and their owners every day. In providing care, Mieshelle says her primary goal is to “partner with cat owners so that they feel empowered to manage their cat’s behavioral health effectively.”  Cats are still the most misunderstood companion animal putting them at the greatest risk.  Even with the increase in cat popularity making them the most common household pet, they are considerably underserved when it comes to behavior help.  Mieshelle’s partner, who is also a veterinarian, says there is definitely a large void in general veterinary medicine when it comes to behavior care for both cats and dogs.
