Mucki is a 5 year-old tomcat. He is friendly, likes humans, talks a lot and he is very quick of apprehension. During the last 5 years he has studied human behavior, especially that of his housemate. He is primarily interested in classical and operant conditioning of his housemate’s feeding and cuddling behavior, as well as supporting her working behavior. He already found relevant mechanisms of shaping her behavior going far beyond state of the art research findings. At the moment he is developing a mindfulness based intervention program, based on MBSR with a focus on training perception of interoceptive body signals, multisensory integration and positive evaluation of one’s body. He is successfully supporting emotion regulation of his human mate, and...by the way, he is the sweetest, and most wonderful cat in the world. (He knows that his intervention program is working well...)
