Can you tell if a cat will be friendly, aggressive or laid-back simply by taking a quick look at its color? That question has perplexed cat owners and scientists alike for years. Although it’s possible that coat color may play a role in personality, it’s also important to consider other factors when you’re considering adding a new kitty to your home.

Does Color Play a Role?

Since cats are never going to answer that question, scientists turned to pet owners for their input. University of California, Berkeley researchers surveyed 189 cat owners in a study published in the October 2012 edition of Anthrozoos. Orange cats were regarded as the friendliest by respondents, while white cats were labeled aloof, and tortoiseshell cats were thought to have too much “attitude.”

The subject was revisited in a University of California Davis study a few years later. This time, results were tabulated from 1,274 completed surveys. The surveys asked cat owners to rate their pets’ level of aggression at home, while being handled and during veterinary visits.

The most aggressive cats in all three settings were females with gray-and-white, black-and-white or orange coats and calico cats. Gray-and-white cats exhibited the highest levels of aggression during visits to the vet. The survey also revealed that black-and-white cats were most likely to react negatively when handled, while calicos were more likely to become irritated. Black, white, gray and tabby cats were rated lowest on the aggression scale.

Although these studies offer some interesting information, they don’t provide a definitive answer regarding whether certain personality traits are associated with specific coat colors. Respondents provided answers based on their particular experiences. It’s possible that what one person viewed as aggressive behavior was regarded as playfulness by another.

You probably noticed that cat owners in the University of California, Berkeley study thought orange cats were the friendliest, while respondents in the University of California, Davis study added the felines to the “most aggressive” category. Because cats have distinct personalities, just as people do, it’s not surprising that there were differences in opinion between the two studies.

What Factors Influence Personality?

Your cat’s early life plays an important role in the development of his or her personality. Kittens don’t develop a fear of humans if they interact with people between the ages of 3 and 9 weeks, according to the American Association of Feline Practitioners. If socialization with humans is delayed, kittens can become fearful or timid cats. In some cases, they’ll eventually overcome their fears, but may still be a little uncomfortable around strangers.

Cats also inherit traits from their parents. If one or both parents are laid-back and friendly, their kittens may also possess those traits. Similarly, cats that are timid or jumpy, despite socializing with people when they were kittens, may have inherited the behavior from a parent.

Other factors may also play a role in the perception of a cat’s personality. For example, some of the white cats labeled “aloof” by University of California, Berkeley survey respondents may actually have hearing problems. Sixty-five to 85 percent of white cats with two blue eyes are deaf, 40 percent of white cats with one blue eye are deaf, and 17 to 22 percent of white cats without blue eyes are deaf, according to Cornell University College of Veterinary Medicine.

Some white cats affected by hearing loss may only be deaf in one ear. Although cats with partial hearing loss may seem perfectly fine, they may have difficulty hearing you when you call to them from a different room or might not respond if you speak into their bad ear. If you’re not aware that these cats have hearing problems, you might assume that they aren’t very friendly.
