Meet Billy, a 39-year-old horse with exactly three working teeth...

''Meet Billy, a 39-year-old horse with exactly three working teeth and the physique of a coat hanger.

He’d lost so much weight you could play xylophone on his ribs. Then I discovered HayCare from Simple System Horse Feeds: beautiful, nutritious mash, magic that doesn’t require actual chewing.

First bucket down, Billy inhaled it like a uni student with free pizza and looked at me as if to say, “You waited 39 years to feed me this? Rude.”

Three weeks later the ribs had disappeared, the coat gleamed, and the old man started trotting around the field like he’d just discovered Red Bull.

Yesterday he attempted a buck (more of a hiccup with hooves), gave the youngsters next door the smuggest look imaginable, and practically winked at me.

Billy is now officially 39 going on 20, living proof that the secret to eternal youth is a feed softer than his remaining teeth and twice as delicious.''
