my three cats

Once long ago, about six years ago, I got my first cat.
Her name was Boo.
At first she just hid under the bed.
As months went by, nothing changed,
Until we got two more cats,
The weirdo brothers, Sparky and Ren.
Boo was the first to have a look at them.
At first they ignored each other,
Until Ren started to annoy Boo again and again.
And even today they still fight,
With Sparky watching from the side lines.
I have some pretty strange cats,
But I love them.
