Helen is a rescue cat, she is 100% deaf and sight in one eye isn’t very good. She was just dropped in the neighborhood and could barely walk and weighed just 6 pounds. There is a tumor in one ear that requires bi-weekly visits to vet for cleaning. She remains deaf(both ears) but requires this for quality of life. She now weighs 14+ lbs, and is the best cat I’ve ever owned. My wife is actually jealous that I give her more attention than her. Don’t care what it cost me each month for vet.
