When cats bite or scratch, they are attempting to communicate something to you. Wilbourn, a cat therapist, was a trailblazer in the ability to listen to them. Carole Wilbourn, who labeled herself a cat therapist and was recognized for her talent in interpreting the emotional world of cats, as puzzling as it might sound, passed away in December. 23 at her residence in Manhattan. She was 84 years old. Her sister, Gail Mutrux, confirmed her passing. Ms. Wilbourn’s patients destroyed sofas, toilet paper, and romantic partners. They dirtied the rugs and bedding. They raced over their sleeping humans in the early morning hours. They hissed at infants, dogs, and other felines. They gnawed on electrical cables.
