My blind cat Fluffy, was a survivor. He had an accident when he was about 2 years old, resulting in losing his sight. We do not know what happened, but he found his way home somehow and we saw what had happened, so we went immediately to the vet. The vet did his best but he had lost his sight. However, being a feline, he began to find his way around, probably by smell and noise and lived until he was approximately 12 years old. We would hang a harness on a pole outside attached to his collar and he could at least enjoy the outside. We had another two cats, but somehow they seemed to live together we no great problem.
