## About The Pull Request
The `/datum/pet_command/protect_owner` behaviour did not have any
validation for if the person who attacked you was yourself.
The three mobs which used this behaviour would sometimes be capable of
seeing you accidentally slap yourself with a burrito and decide that
this meant that you needed to be protected from this hideous and violent
aggressor (yourself), and would then start trying to kill you.
If you had multiple minebots they would then start attacking each other
in a fit of jealous and protective rage, which I think was quite funny
but isn't supposed to be how the game works.
