Fridge Brilliance: In one segment, Kit and René's coaches each make their case for their respective athletes. René's coach says there should be blood tests after the race, and yanks a box marked "Catnip" out from Kit's coach's vest. The visual implication is that Kit cheated.
Fridge Horror: At one point you see an elephant wearing a fur coat. Considering that all the animals we see in the cartoon are sentient, this is basically the equivalent of one of us wearing clothes made of human skin.
