For almost a week now, my 11 year old cat, Pepper has not looked well. She has her inner eyelid showing constantly, and her eyes are very runny. She is an indoor/outdoor cat, so I'm not sure if she just caught something outside. I've read a lot about possible respiratory infections or more serious things,so if anyone has any ideas about what it might be, please let me know. I also attached a photo of her eye.
