White cats with blue eyes get their coloring from mutations in a gene called KIT. The blue eyes result from a cellular issue: these irises have fewer melanocytes, which are cells that make pigment. These same cells create skin pigment and play a role in inner-ear functioning. Therefore, cats with fewer melanocytes—white cats with blue eyes—may not have enough of the cells for their hearing to function properly, Dr. Lyons says. White cats have a genetic makeup similar to albino humans, who lack pigment; this gives them some vulnerabilities, like sensitivity to UV light.

An estimated 40 percent of white cats with blue eyes are deaf, which is high. And Chat Blanc is also much paler than he is as Adrien/Chat Noir.
