Many (But Not All) White Cats Are Deaf

The same genetic factors that give white cats their snowy coats and unique eye colors can also cause total or partial deafness in many kitties. It's believed that the ear closest to the "oddly" colored eye (or both ears if both eyes are uniquely colored) will be the ear with deafness.

If your cat is partially or completely deaf, there are several precautions you must take to keep them safe. Be careful not to startle them and use visual signs rather than verbal signs to communicate. It's also best to keep a partially deaf or fully deaf cat indoors at all times; it may have trouble avoiding hazards or protecting himself from potential predators.
