Oh that poor boy! Im glad you have him now. I just dont see how no one noticed this sooner? Im sure he will adjust in time. I have no experience with blind cats, only a dog. I rescued her from a breeding kennel!! She always done quite well and in time knew her home very well. She would even get excited and jump around, it was the cutest thing. (I found a home with a sweet lday who can't have kids, spoiled rotten)

Maybe encourage him with treats or something to walk farther in a strait line? Maybe that will help him realize that he has more freedom. I just feel so bad for him. I cant imagine being in a small room, that he can only go up in and he couldnt see a thing. I know he is in a good place now, im sure it wont take long for him to figure it all out.
