The cat ate my pizza.
It wasn't just any pizza, home made crust, home made white sauce, and a generous topping of fresh mushrooms, lightly sautéed before putting on the pizza.
I was saving half for today and late last night, after the pizza had cooled, I went to put it in the frig, and all the mushrooms were gone.
Maybe cats have a built in umami detector, because I really didn't know that cats liked fungi.
Do you have any evidence pro or con?
