My daughter is watching Tom and Jerry.
"Are mice vegan?"
"They eat grains and nuts and maybe tree bark. They eat vegetables too. But I think they eat anything when they are really hungry."
"Cartoon mice eat cheese."
"Yes, that makes them vegetarian but not vegan."
"Vegans eat nothing that comes out of an animal. Do you know what cheese is made of?"
"Well yes, cheese is made of milk, which comes out of cows, but cows only eat plants, so technically milk is only plants metamorphosed. That makes mice practically vegan."
"..." <--- Mommy is speechless.
