You will need to get it from a vet. Do you have a vet? You need to do this asap. Have you been able to use a warm cloth to get their eyes open for now?
It's really expensive. Yes we do have a vet. She said to wait a couple days and see if it goes away, I don't think it will. If it doesn't we will go back and we will get some.
We got free medicine from the vet, because we took our other cat to get it fixed and The doctor said that he would call us about five on Saturday and said it was a riskier surgery...and never called us, soooo yea.
