Marigold bakes a cake

Marigold the cat loves Mondays, for that is when he bakes cakes! With his favorite recipe in front of him, he rolls up his sleeves and gets down to it. He whips up egg whites ... Easy. He adds a cup of milk... Peasy. The he sprinkles in just a pinch of... of finch?! That's not right at all! Neither are the smidgeons of pigeons or the spoonsfull of loons. Clearly a chase is in order! Yet all that leads to is a spectacularly messy kitchen. And no cake.
