Cerberus

If i were to obtain a pet dog
The best deal around
Was buy one
Get two free!
All in one package
Instead of a four-legged friend
A three-headed Cerberus fiend!
This wouldn't work for me though
I prefer cats!
And imagine patting your pet on the heads?
I have only two hands
I'd worry at the head not patted
Would it get jealous
And perhaps eat me?
