This is the child of a cat me and my sister found a little over a year ago this one is around 5mths old and is now showing these problems with her eyes. She is the youngest of thriplets and the other two only had pink eye in the first 1.5 mths of walking around on their own

The inside of her eyelids is swelling amd making it hard for her to see this is it on a good day and i am un able to go to a vet. I dont know if its important but the mother when we found her is missing an eye
