I got a Holland Lop bunny about 4 months ago and she had a tiny black spot on her eyeball where her normal color blue eye was. Well I noticed about a month ago it had covered just half her eye. Then I noticed a few nights ago her whole eyeball was black instead of the gorgeous blue eye that made me fall in love with her. She is now 7 months old. Can anyone tell me why only one of her eyes would go blind when she is so young? She will be 8 months old on November 19th 2012.
