Any clue as to why my cat becomes a bit of a mooch when I'm eating strawberries?

I was sitting on my couch with a bowl of fresh strawberries in my lap. He stuck his big mug into the bowl and started to chomp at them. Anytime that I’m eating strawberries, he is right on me, and gets a bit crazy (rolling around like how he is with catnip). I didn’t know that cats liked them!!
