Allow yourself to think freely, and question why you might be thinking what you are, and why you react the way you do. Emotions are what conduct our train of thoughts, bottled up anger for example will strive to be released one way or another. In reference to the cat, maybe you feel a deep sense of unjustified pain that wants to be let loose and seen for what it is, so to speak, causing you to think the same way irrationally...
Like if there was a song that consistently brought up bad memories, listening to it in a new setting those previous emotions must be faced, rationalized with, made sense of, and new ones created which do become more prevailing.
I dont think thats pain,its probably more of some primal thing,like cat is potential food and only people to not be removed from gen pool were obviously those having food
