Milking Cats????

As I was preparing dinner tonight my 7 yo dd comes skipping asking me "Mommy, why can the kittens get milk from Marble (our cat) and I cant". Not really paying attention I said, "Because we weren't meant to milk cats, their teats are to small." Then I thought about her question. "You tried to milk the cat?", I asked. "Yes" she replied. "With your fingers????" "No, I tried to drink milk from her!" "With your mouth" "Yeps" "Please dont try that again!"
