There really is chemistry between you and the cat - scientists have found a hormonal connection. Researchers from Kyoto University measured oxytocin and cortisol in 19 owners and 29 cats over the course of a month. Levels of bonding-related oxytocin in humans and pets have been shown to correlate. A higher score in the cat was also associated with less stress and less negative mood in the owner. At the same time, cats did not turn out to be a hormonal "mirror" of their owners' stress: the connection with cortisol was weak. So there is chemistry between you, but it cannot be said that the cat really absorbs your experiences.
