Sense Sonnet - Chiller

 The Order of the Departure

A master and a mistress that

In their home I am resident,

A nice enough place for this cat.

I don't have to pay any rent.

She is my fav'rite of the two.

Both of us stay healthy and fit.

He is kind of a slobaroo.

She and I move while he does sit.

If he just up and went away,

Upset 'bout that I would not be.

And it could happen any day

Based on a secret shared with me.

My mistress told me on a whim,

She is slowly poisoning him.
