Maybe about half of the included 140 pieces are rhymed and about half unrhymed. Aspects of rhythm may be detectable, but blatant meter generally seems unlikely. Here are a couple of perhaps representative samples:
DOGS
Dogs daily seem
to have managed.
From the earliest
of life's moments
a dog's howl
emanates fiercely.
In the lust
and luxury
ruling the planet
few canine barks
might be unperemptory.
HOGS
Hogs that were called
became appalled.
The human condition
implied sedition.
To be a pig
stayed rather big,
but snout on snout
wanted out.
A true main sorrow
was mere tomorrow.
