Cremorne was a difficult horse to train, owing to his extreme laziness: he was known to fall asleep during breaks in exercise. He also had an apparently insatiable appetite and would eat anything edible within his range. On one occasion he contracted a near-fatal bout of colic after eating all of his bedding straw.[3]

Maybe he was just more interested in naps and snacks than lady horses. 🤷‍♂️
