Cat has continuously dilated pupils

by Anonymous

My kitten was found feral at what we assume was 8 weeks. I have never, not once, even with shining a flash light in her eyes, seen her pupils "slit." Her eyes are ALWAYS dilated.

She is Siamese and has bright blue eyes. She seems to be doing perfectly, except I just now realized that cat eyes are supposed to get smaller in light?? Is there something wrong?
