Black cats are often scorned

Bad luck assigned as trait

But I knew one that charmed

Let's set the record straight

He was all black except

For white star on his chest

A white and tiny fleck

Too tiny for accent

He was my son's best friend

When son felt all alone

He helped my son to mend

Until my son was grown

And when my son felt lost

And chaos swirled around

Cat chased away the frost

Until my son felt sound

The cat's head would pop out

From blanket as son slept

That left me with no doubt

The love that both them kept

A constant stable force

He even hugged my boy

Ally who stayed the course

And brought my son great joy

How does on say "Thank you"

So creature understands

The debt you feel is owed

Which feels like shifting sand
