Just as with humans, a cat’s eyesight will start to deteriorate as he gets older. You may see him bumping into things or not noticing people walking by. Basically, the only way you can help your cat through this time is to be patient with him. You will need to keep a closer eye on him to make sure he doesn’t hurt himself and make some adjustments in the house to help him get around, if necessary. Keep in mind that cats tend to be very prideful, so try to be sensitive of your kitty’s feelings during this difficult time.
