Not trying to be rude or whatnot, genuine question. Indian folks have a subconscious headbobble to communicate various types of pleasure, displeasure, confusion etc… Animals also mimic behaviours and motions performed by humans depending on the scenario.
Do your cats adopt the head bobble to communicate desires or displeasure while you are talking/communicating with them?
Not indian, nor cat, but married into indian family. I now have headbobbles. My family makes me do tricks at family gatherings for laughs.
