This morning when I went to give my cat food, I noticed that her eyelid was swollen and that her eye is leaking liquid. What should I do?
Take her immediately to the vet. Eye problems in cats can become serious and obviously eyes are so important. You cannot know, without a vet visit, whether she has a corneal ulcer, conjunctivitis, uveitis, or one of many possible eye diseases.
There is almost never a case involving an eye problem in a cat that doesn't need some type of treatment. Also, the longer it goes undiagnosed and untreated, the more serious the condition can become, even leading to blindness in some cases.
