How do you know if a cat is going blind?
I have a male silver tip persian (BayLee) who is 13-15 years old. He loves the outdoors and we occasionally allow him to stay outside overnight. Last night, in particular was a cold night (35 degrees) and when he came in this morning, his one eye was a total different color than the other. He has yellow eyes. One was still yellow, but the other was a VERY dark brown and seemed to be red when lifting the brow. We didn't know if this could be a sign of blindness, death, or something that occurs when they get old. Any advice you can provide will be GREATLY appreciated. Thx.
