From the Horse’s Mouth

Since I come from where the horses live,
you’ll find these words superlative.

More than one savvy equine
has told me that it’s asinine
to expect a horse to dine
on hamburger or pork or fishes,
for it goes against his wishes.

If he gives in to your urges,
you can soon expect his purges.
Burger, hot dog, tail or fin
will soon come out where it’s gone in!
Don’t seek to change what horses eat,
for if you do, you’ll meet defeat.

Word prompts today are vivid, urge, asinine, defeat and superlative.
