Diego was turned in by a family who simply wasn't home enough to give him the love and attention he needed. Kittens need affection to be socialized, and they return the love 100-fold. Diego is a total love muffin and is used to other cats because he spent time with his siblings growing up. As a result, he plays and interacts with people the way he does with kittens - so he gives little love nips. Oh Diego - silly kitten. If you've never owned a black cat, you should certainly consider it. They tend to be THE MOST LOVING kitties.
Centuries of superstition in the U.S. have given the black cat a bad name. But in other countries such as England and Japan, the black cat is considered to be good luck! In fact, Charles I of England owned a black cat and loved it so much, the cat was kept under constant guard. When the cat became ill and died, it just so happened that Charles was arrested the next day.... How's that for luck?!
Due to the association of black cats with witches and other "dark forces" in the United States, there is an increase in abuse of black cats around the time of Halloween. Many people will adopt black cats for "decoration" and then release them. For this reason, many animal rescues do not make black cats available for adoption during the month of October.
