Does your all white cat have blue eyes? Do they sometimes not come when called? Does it seem like they are not always listening? If you answered yes to any of these questions, then you might be dealing with something a little bigger than simply being ignored…deafness. This topic is actually news to me too. I didn’t know hereditary deafness was a major concern in white cats with blue eyes until one of my Facebook followers mentioned something to me. Per the Cornell Feline Heath Center, “researchers found that only 17 to 22 percent of white cats with non-blue eyes are born deaf. The percentage rises to 40 percent if the cat has one blue eye, while upwards of 65 to 85 percent of all-white cats with both eyes blue are deaf.” Here are a few more things to note if your furry feline is white and has one or both eyes blue.
