Florida Cat Behaviorist Testimonials 

“It took years to find help for my cat’s urination and marking issue.  He had been through every conceivable treatment (and some which had significant side effects) before working with The Cat Behavior Clinic.  After years of suffering we finally found appropriate help for our kitty and all with one phone call.  Thank you to The Cat Behavior Clinic.  You were our last resort.  You clearly know cats and are advocates for their behavioral happiness (and the owners too!)”.  Nancy I.  Florida  (read 350 more testimonials here).

Cat Behaviorist Mieshelle

World-renowned Innovators of the Cat Behaviorist Specialty

Zoom or Phone Consultations with Dr. Jim Shultz and Oxford-trained Certified Cat Behaviorist Mieshelle Nagelschneider.  They are the founders of the “Cat Behaviorist” specialty and the first cat-only behavior practice serving Florida cat owners (and the entire United States). To date, cats are very underserved when it comes to behavior help and there are still only a handful of cats exclusively behavior services in the United States. 

The Cat Behavior Clinic goes beyond the obvious behavior strategies to change a cat’s behavior and offers complete and holistic behavior plans that apply training modalities that are based on your cat’s feline evolutionary biology.  Urination, defecation, urine spray-marking and aggression are the most common issues the clinic addresses.

Florida Cat Behaviorist Testimonials

Orange Cats at The Cat Behavior Clinic

Cat Behavior Testimonial:  Thanks to your cat behaviorist, we now have a urine-free cat family just like she said we would.  Our home no longer smells like cat urine and the added bonus is that our cats are so much happier.  The information provided is no where on the internet.  The consultation program was very worth our time and investment and we feel so lucky to have worked with Mieshelle.   Regards, The Taylor Cat Family, Miami, Florida

Florida Cat Behavior Review:  Well,  I can’t believe it took just 3 days, but it was that easy.  We DID NOT have to add extra litter boxes either.  Mieshelle is brilliant and saw the problems right away.  It’s week 7 and not one accident outside the box.  Claudine has begun playing again with her toys and she actually sits next to Augustus now.  This is unheard of and I can’t thank you enough.   All the best, One grateful and enlightened cat owner.  Paula S.  Orlando, Florida

Florida Cat Behavior Review:  I considered myself a very savvy cat owner having owned multiple cats my entire life, but I have learned so much from Mieshelle, your cat behaviorist.  When we rescued the feral cats from our Florida golf course, we had no idea what we were in for.  The urine almost ruined our home and the cats fighting almost ended our marriage.  Mieshelle became the light in the very small world of cat behavior knowledge available to cat owners.  We have recommended your practice to our Florida veterinarian and we will contact you after we return from our vacation to schedule our last call.  Thank you for all that you do.  Mary S. – Tampa, Florida
