cat with round pupils
« on: 07/08/2013 05:41:24 »
I have a cat the is a mix between Siamese and something else, but I notice she has round pupils. Can anyone tell me why hers is round and other cats eyes are slitted?

Round pupils are characteristic of "big cats" and many oriental breeds of domestic cat. They seem to be associated with "canine-like" behaviours compared with the typical feline behaviour patterns of a small European moggie.

IIRC the slit pupil makes kittens very sensitive to horizontal movement but requires exceptional retinal sensitivity for night hunting, whereas the round-pupil cats tend to hunt by day and  by pouncing on static prey rather than swiping moving objects.
