I have a kitten that is blind. Her mama was a stray and I have fed her by hand since she was 2 or 3 weeks old. She is about 3 months old now. She only has one eye (her left one) and it has a bad cataract. Her right eye is just an empty socket. She can see shapes and light and dark but not much else. She is extremely independent though and goea about her business like she has 20 / 20 vision. Her best buddy is my maltese mix Nigel. They play by the hours. She actually puts her entire head in his mouth......no the least bit afraid he will hurt her. The two of them bring me hours of fun and laughter and more love then I can explain!
