When they are cleaning their feets and spread all there little toes out
When they smelled something weird and make a stinky face
When they walk up to you making little chirpy purrs enquiry
When they get distracted by a noise mid - lick and a tongue blep occurs
When they see a bird and do that ekekekk thing
When they become possessed by the devil and tear around the house with demonic speed and then pause mid-vicious-attack of a scratching pole to whip their head around and fix you with their all-pupil stare of unhinged terror..
