A Familiar is an animal who has a spiritual bond with a witch often they are not only a familiar but also the family pet.
My personal familiar is one that is near and dear to my heart. He is not only my familiar but our family pet and a great source of protection, safety, and love. He is a mix breed I rescued from the pound when he was only 6 weeks old. Shepard and Lab he is a big boy but he is loving and energetic protective of my son and always ready for an adventure.
He is family as much as my son, and joins us on all our trips into the woods.
