Hi everone I'm new here. To make a very long story short, our neighbor moved and left 3 cats behind. We stared feeding them outside. Back in april one stopped eating. We got him in a carrier and to make another long and horrific story short the cat had a gallbladder infection that caused liver failure. We had to go to 2 differnt vets to find out what was wrong and you can only imagin how much we had to put on our credit card. Any way by the grace of God he is 100% better and now is a indoor cat. He still has his 2 brothers outside, we want to bring them inside too. I was just going to give them a dewormer and let them in but I noticed one of the brother's 3rd eye lid is showing. It nerver showed before. We don't know what to do. We really can't afford any more high priced vets. Plus I am worried if we take him to the vet he will be so scared when we bring him home he won't eat and go into liver failure like the first one we rescued. I don't think the neighbor that left him took him to the vet in years, he has been fixed but that's all the neighbor did for him. I guess my question is does anyone know what it means when a cat's 3rd eye lid shows. I would appericate any advice. Thank you
