Kitty Birthday Cake?

My cats are approaching their 1st birthday and I was wanting to make a kitty safe birthday cake for them. I have looked online but couldn't find any recipies. Does anyone have any ideas or recipies for a kitty cake?

Thanks

We used to make a "kitty cake" for my RB cat Katy on her birthday. We'd take a can of wet cat food, and open it onto a plate so that it stays in one piece. We'd put a piece of American cheese, cut into a circle on top for "icing" and put a candle in it. She loved it! Neither of my cats now like the wet food that will stay in one round blob, they like the chunky kind, so I haven't made one in awhile.
