It is dangerous to ascribe human emotions to animals. However, when an alpha pair are about to mate, they go through a period of intense courtship that has many parallels to 'falling in love. 'Courting' pairs sleep close together and often touch each other. They make quiet, wailing sounds and constantly touch their noses. They nibble at each other's fur and even walk close together. Like human lovers, they avoid the company of others and only want to be with one another.
