Cats with obsessive-compulsive disorder
It seems that cats also have OCD (obsessive-compulsive disorder). In this state, obsessive thoughts appear in the head that prompt actions that cannot be resisted. For example, a person simply cannot force himself to step on cracks in the pavement while walking. Or it will be monstrously unbearable for him to look at a cup that is not on a stand. So cats are met with similar obsessive states. Video evidence.
