I'm sorry to ask a health question about a cat, but I figured dog experience would apply in this case. I think one of our kittens has very poor eyesight. At first we thought she just was very cautious (you reach to pet her and she startles, you recline a chair she jumps away ect). She has never been abused, and once you touch her, she recognizes it is you, she is all about belly rubs. But I notice she has to feel her way past pillows or blankets on the couch, and she will bang into the corner of a door ect. She doesn't seem to be unhappy or ill, but I think poor eyesight would explain her caution. Is there a way to test vision?
