Most of the time when my cat goes to sniff something she hits it with her nose. She did this to a friend of mine, and he suggested that she may not see well. She has never run into anything. She is six, and I don't really think so, but she does hit things occasionally when she tries to sniff them. Is that just a blind spot, like right between our eyes? Her pupils adjust to light and aren't big. She narrows them to slits and will widen them at night. Does she just have trouble knowing where things are right in front of her?
