This shocked me at first, because I never remembered if the bus had cat nipplies or not. This was never a thought at five. But then I saw kittenbuses and I exploded. Nursing kittenbuses is bonus! The peeping mice look confused. A very fun piece overall of one of my favorite characters of that story. I always wanted a ride in that cat. And right now I want to make a picture of some mice riding in the kitten bus.
