My 8 month female panther has recently developed an eye problem. I don't know how else to describe other than her eyelid seems to be big/loose on her eye. I can see her eye moving beneath the lid and it will center with the slit in her eye will appear normal, however then it will slide back and her eye no longer is visible. This started about a week ago and has been going back and forth in getting better and worse. Any insight on what this may be or what should be done? Pictures can be provided if it will help
