My cat absolutely gets into a flow state when something triggers her to groom herself fully. Other than significant external pressure to stop (getting picked up and/or prevented from grooming) she will persist in grooming even if it isn't herself: my arm if I picked her up, a blanket if I relocate her, the air for a few seconds until she breaks out of the "loop".
