Foundational Behavior Plan Elements Based on Scientific Research Study of Cat Behavior

Mieshelle was the first “Cat Behaviorist” in the U.S. and founder of the first cat-only behavior practice in Texas, and known as the innovator of the cat behaviorist specialty for 25 years.  Mieshelle Nagelschneider studied animal behavior at Oxford University, The Royal School of Veterinary Studies at the University of Edinburgh.  Her animal study experience at Harvard University has also enabled her to help cat owners think more scientifically about their cat’s behavior (read more here) and to achieve a 95% success rate and hundreds of testimonials for solving cat urination, defecation, urine-marking and inter-cat aggression issues.  Mieshelle and our veterinarian scientifically observe and analyze cat behavior from a behavioral cognitive, ethological, and feline evolutionary point of view.  The behavior plans are involved from an animal psychology perspective, but straightforward for cat owners to implement.  Our veterinarian can conduct vet-to-vet remote services.
