WOW!! I am glad you found his owners, but what kind of a person allows a cat with a tumor, poor health and memory loss to just wander off??? That just makes me mad! I just cant believe it! I m glad that you were able to get him back on his feet! not sure how long that will last if his owners just let him run off again. You have a very generous heart! Smokey will remember his savior, I am sure!
