what are cat pupils called
Best Answer: Great question! All cats have vertical pupils because they are nocturnal, but different breeds have different shaped eyes. So, when a cat's pupils dilate, it may seem as though they have rounder eyes. Cats pupils will dilate for different reasons. Obviously pupils react to light, but they will also dilate when something of interest comes into view, like while they are hunting or about to pounce on a toy. They will also dilate if they are scared or surprised.
