Hello, my poor little kitty has a bad eye. We noticed the other night and he went to the vet the next day and he has been given Tiacil, an opthalmic solution. He had the dye and the ultraviolet light and that is what vet prescribed. I was at work but my bf took him, thing is I wasn't there to ask any questions and I am quite anxious to get an idea of how serious this is and quickly it could heal. He is a domestic longish hair. He is in good spirits, playing and isn't showing any signs of pain, no squinting or rubbing. His eye is discoloured, darker, and looks like it could be slightly swollen. I am giving him the Tiacil in drops three times a day and he is brilliant with letting me do it, bless him. Has anyone elses cat had this? Could I have prevented this? It could have been a scratch or sting or something? I love my little boy so much, any advice or info from anyone would be greatly appreciated.
