Actually, I tried just wiping over her closed lid with a cool wash cloth but I could tell that she didn't want me to do anything else. I waited the night out and in the morning, her eye was fully opened and she stopped squinting. What a relief. I guess she got it out by herself? Good thing because I was planning to call the vet that morning to bring her in. (Boy she would have not liked that.....she freaks out when we need to bring her in.) Thanks everyone for your help!
