So, Misty made out pretty good yesterday. The vet looked in her both of her eyes and said she does in fact have nuclear sclerosis and is free of cataracts. She said her eyes aren't that bad though, and that her sight should be just fine for right now. I am very happy it isn't cataracts, but, at the same time, it still breaks my heart because this is the first time Misty has ever shown her age.
All I can do is hope the she keeps her sight as long into her upper years as possible.
Thank you again for your help!
