Concatenate--by Erin Bregman

to join sequentially; linked together as in a chain (v.)

You've likely heard by now
of that anti-gravity machine theory
based on falling cats
and buttered toast,
and I tell you straight I saw my cousin try it once
with his cat who had just given birth
to a litter of ten.
And when he dropped her
with buttered toast tied to her back
she never hit the ground but did manage to
grab ahold of her eldest born,
mouth to nape of the neck like cats do,
and that eldest, he managed to grab ahold of that
ball of string he'd been batting around and
his youngest sister managed to
keep her hold on that string and
I sat there watching as they rose,
and disappeared into the night sky.
