I know the witnesses piss me off showing up early in the morning on a weekend (Up before 10AM on Sunday morn NEVER) they came to my door 5 weeks in a row... So on the sixth week I put a bottle of ketchup by the front door... When they came knocking I covered my hands in Ketchup and nicely asked if they could come back after I finish sacrificing the cat.... They never bothered me again... But I did get a visit from the humane society...
P.S No Cats where harmed during this incident...
