I've actually heard that Meezers tend to be a bit... dumb... actually. As Molly is only a half breed, I have no idea if this is true, however, i have noticed and heard tell that cats with blue eyes tend to have vision problems, and this is certainly evident in Molly, as she has problems tracking toys as they move, unless they are doing so at a certain angle from her eye. She also misjudges distance at night.
