Third eyelid showing in kittens
My two boys are just over 10 weeks old, and I notice that their third eyelid is sometimes showing. It seems to be mostly when they are tired, and they are otherwise healthy, bouncy, normal kittens. They are eating, playing and using the litterbox fine. They've only been home for 4 days, could it be due to residual stress from the move away from their mum?
I have a vets appointment for tomorrow morning, but just wondered if anyone had any thoughts in the meantime?
