My one cat who is a Balinese (breed of Siamese) has vision problems. One of her optic nerves (or something like that) didn't develop properly. If you look at her eyes from the side they shake often. She certainly isn't blind, but she has to get pretty close to some things and usually smells things to identify them. She hides when someone comes to the door, etc. Is very afraid of strangers. Also, she hides during storms (my other cats don't even notice them). But she is also the sweetest, cuddliest thing every. Her fur is soft like a bunny rabbit.
