Yeah..my first cat, Jax, who's about 12 years old went blind 2 days ago. I took him to the vet, and he said it is caused by high blood pressure, or uveitis or something like that. He gave us medicine to give him three times a day (forever...) to have a chance of getting his sight back. See, his retnas detached from the rest of his eyes, but if they didn't completely detach, the medicine will help them reattach. What do you think the chances of him seeing again are?
