J.A. Lindon composed this remarkable pair of monosyllabic poems in 1969. The two read the same, but each has its own rhyme scheme, and each is a distinct acrostic, the first letter of each line spelling out the title.

Cats, Cats, Cats, Cats!

Cats come with mews,
All have sharp claws,
They air their views.
Stray soon from laws,
Climb wall. Each tom
And each mog — grand
Thieves — munch meal from
Scamp’s lunch. Scamp planned …

Chain off, he might
Aim at a rout,
Touch mogs and bite
Such prime bits out!
Chance came. Grey dawn.
At once left mat.
The deuce! On lawn -­
Scamp loose — no cat!

Chase ’em, Scamp, Go On!

Cats come with mews, all
Have sharp claws, they
Air their views, stray
Soon from laws, climb wall.

Each tom and
Each mog — grand thieves — munch
Meal from Scamp’s lunch.
Scamp planned …

Chain off, he might aim
At a rout, touch
Mogs and bite such
Prime bits out. Chance came.

Grey dawn. At
Once left mat. The deuce!
On lawn — Scamp loose -­
No cat!
