Siamese Cat Eyes Always Dilated. He's about a year and a half old now. I know that i read that most cats with blue eyes are either blind or deaf or both.
My cat eyes are always round or dilated since birth. Dilation should be an exception, not the rule. Cat eyes should remain in a neutral state for the majority of a day.
If unequal pupils occur suddenly, bring your cat to a veterinary clinic or animal hospital immediately as eyesight can be permanently damaged if the problem is not rectified.
Cats usually have some variety of green, yellow, or blue eyes. I always have loved her eyes,shes the only cat i have with greenish eyes and the other night i was sitting playing my xbox with my lamp only on and i looked at her and 1 eye looks normal color and the other is a bright yellow/green like it looks like one eye is a flash light. If you notice changes in your cat's iris or the appearance of splotches of other colors, contact your vet. They open and close much faster than a round pupil, which allows for much more light to enter the eyes.
