A Nice Furry One

A doctor had just finished a marathon shagging session with one of his patients.

He was resting afterwards and was feeling a bit guilty because he thought it wasn't really ethical to screw one of his patients.

However, a little voice in his head said "Lots of other doctors have sex with their patients so its not like you're the first..."

This made the doctor feel a bit better until another voice in his head said, "but they probably weren't vets."
