Me and my friend are going to an Anime Convention as the Zero Brothers from Loveless (Natsuo and Youji) and we need to find animated cat ears, not the regular kind, robotically animated cat ears. Preferably in light blue and burgundy.
Not entirely sure what you mean by "animated," but after looking at pictures and video clips, I think these might work really well for you if you have time to order them: http://www.nekochii.com/products/nekomimi.html
They have tons of different colors, including "sky" for your light blue and "dark wine" for your burgundy.
