Can animals READ so they can cross where they should?

Ellie mo . o . o . o . od,
wasn’t up to speed,
hadn’t learned to read,
crossed at the ‘deer’ sign—
landed in the weeds.

The bull w . . o . . o . od,
stomped those weeds silly,
lip-puckered dilly,
caught it on the sign—
now … call him Milly.

Milly mo . o . o . o . ved
let Ellie pass by
saw tears in her eye
aching to cross o’er
where grass grew more high.

Ellie sw . o . o . ned,
Millie took the hint,
on the street did sprint
crossed at the wrong time.
Millie screamed … car dent.

Driver mo . o . o . aned
ain’t cattle crossing,
it says: Elks Flossing.
A herd of elks came,
heard the man bossing.

Ellie stro . o . olled
(all the elks watching
but too busy flossing
in the highway:
Millie, man boxing).

Ellie m o . o . o . od,
screamed: Cattle Crossing
the elks ceased their flossing;
the others their boxing.
Signs how intoxing!
