Let's not forget, folks, since (IIRC) 3.0 Edition, Arudin (or any other wizard or sorcerer) cannot have any creature as a familiar that is not a natural animal of Tiny size (or outside of the list given in the PHB, DMG or of the DM's creation) without the Improved Familiar feat.
Since Kayless advises not to worry about the familiar, I say the case is closed.
