Ball Thieves!
I love the treehouse animal shelter. I occasionally give them some money. In return they send me tons of junk mail telling me what they are up to. One thing they are particularly proud of is their trap-neuter-return program. This is a way of containing the feral cat population and keeping it reasonably healthy. Pretty cool over all, but my lovely wife just pointed out that it would be disconcerting to wake up woozy after being kidnapped, wondering where your balls got to. Now all I can think of are BALL THIEVES!
Of course this is not an urban legend! Beware the ball thieves! Man, I’m never going as a cat for Halloween again.
