A Poem I wrote for school

Cats
In tall sticky grass,
A cat hisses loudly
At a black big dog.
Jumps up in horror
And in pure fright
Races up a tree.
Safe up high
Cat eagerly paces to and fro,
Sits down, licks her paw,
Laughs wickedly at dog below.
Dog is gone,
Cat leaps down,
Clas at nearby fly.
Chases butterfly,
But dog comes back,
And the chase goes on.
