I have an orange long haired-tabby stray who showed up at my house about a year ago. About 2 days ago I noticed her eye looked a little irritated, nothing major. Yesterday by the time she showed up at my house (she usually shows up and stays inside my house from 9 at night until around 5 in the morning and leaves while we're sleeping) it looked a little more pink, but nothing too serious. I read online that cats eyes can get scratched during cat fights which is common and usually goes away within a day or two. She just showed up tonight and her eye looks HORRIBLE. It is VERY swollen, her third eyelid is now covering about 50% of it, it is pretty leaky with some brownish discharge. I'm calling ASAP in the morning to set her up an appointment, was just wondering if anyone had an idea of what it could be?
