The content cat::half closing their eyes, ears forward, often with purring.
relaxed and alert: normal expression.
The ambivalent cat: twitching of ears.
fearful cat: Ears are folded down. In extreme fear, ears will often flatten completely.
The Fleming cat: sneering expression when a male picks up the urine scent of another cat.
The aggressive cat: pupils are fully dilated and mouth is open to hiss.
