I second Kila.
If the only reason you bought him was for your personal magic needs, then that's a bad thing. They are so different than cats and dogs. They need more than what you are giving him, if I understood that post correctly.
If you can't spend time with him, I suggest you give him back or spend more time. :[ I know it's kinda harsh, but you might be ruining that creature's life. :[ He'd be happier bonded to you and getting to interact with you.
