My cat was out for about 3hrs this morning, and comes back with her eye closed. It is a little swollen, but she can open it more than halfway. There is some fluid coming it, but is is just clear. Every couple hours I have been taking a wet paper towel and wiping her eye, then I have been flushing it with water. Is there anything else I can do to help with the swelling, or to not let it get infected? I checked her out and there are no cuts and her eye is a normal color. I'm thinking sh either got something in it, or poked herself in the eye.
