Kitty Themed Cake

I love these challenging cakes but I'd really love to know how to model animals easier.  This was my second attempt on the cat.  The first try was pathetic.  I made this cake back in March and barely remember the flavors.  I belive they were chocolate cake on the bottom tier with raspberry filling and chocolate buttercream and almond cake for the top with almond buttercream filling.  All covered with fondant.  The cat is made out of rice krispy treats and fondant.

I started out with design from the Pink Cake Box http://blog.pinkcakebox.com/pair-of-cats-birthday-cake-2010-04-17.htm and this is what I could do.  Their kitties are obviously much better.
