You may think that a dog or cat without any eyes would never be put up for adoption. In some shelters that may be the case. Not at the San Jose Animal Care Center (SJACC).
At SJACC, the veterinarians evaluate each animal that comes in for medical issues. Being blind is not necessarily an indicator of a medical condition that would prevent an animal from being adopted. As long as the animal is otherwise healthy, being able to see is not necessarily going to impact quality of life, especially for animals that slowly lose their vision over time as is the case for many animals with cataracts.
A recent dog who came into the shelter was surrendered by its owner for euthanasia because the dog had been blind for two years and the owner did not believe that was a good quality of life for the dog.
