Having a pet is one of the great joys of life. It can be very refreshing to interact with another species besides a human being. Animals seem to be a lot less complicated than humans. People that find human interaction a source of anxiety can often take solace in a their cat or dog. Our pets have a unique ability to comfort us without saying a word. Somehow just being able to cuddle with them and look into their eyes is enough to make us feel better after a hard day.
