You morose fool, now the pet will go to pet hell and it will haunt you til your dying day.
I suggest cloves of garlic, wait that's for Dracula...HOLY WATER! That's it. Spritz holy water around your bed before you go to sleep. If you still get haunted, that means the spirit was within the circle of holy water before the circle was complete. If that is the case, then you are screwed.
