Seattle 2021 Testimonial From Dr. Midori Higashi
I consulted Mieshelle for my 4 month old kitten Bun Bun. When we got her, it was like she had never used a litter box. She was peeing/pooping on the carpet, on the bed, on the bathroom floor…I was having to do laundry every single day. I was at my wits end. I did extensive research to find a solution…cat forums, books, youtube videos, etc. I tried everything…different boxes, litter types, etc. She was traumatized every time I would attempt to even place her in the box. Within one week of consulting with Mieshelle, she had fixed our problems. Bun Bun hasn’t had a problem in over 6 weeks. She also helped us integrate a second kitty. Her tips/tricks helped the kitties love each other before they even met. I 100% recommend The Cat Behavior Clinic!

To change a cat’s behavior, it’s important to work with an experienced cat behaviorist, but most importantly, one with formal study in animal behavior that can apply the sciences of genetics, animal psychology, biology, and physiology to effectively correct a cat’s behavior. An effective behavior plan to correct a cat’s behavior long term must be grounded in feline evolutionary biology and gene-encoded behavior.
