Answer:
A form of guidance as a familiar is, should not have to be found but rather, should find you. Just like many things in life, they come when most needed and least expected. A familiar knows its place and is an old soul so it also knows the exact time it should arrive into your life. If it has been a quite long time, and searching is needed, you could start by looking to animals that seem to suit your personality and lifestyle because usually these are factors that go into what your familiar will appear as. Research a little about where certain animals are from and if anything matches up to you as a person. Just make sure to keep your mind, heart, and eyes open because your familiar could arrive at any moment. :)
