Meet Pinky and Burger. They're very loving cats, available for adoption - should what you're looking for in a family pet be rabid and just a teensy smidge demonic.
I love how Officer Bob starts off all cuddly and pro-Pinky, proudly showcasing his finer Pet-of-the-Week points to all kitty-loving kind. Only to emit several shrieks of holy terror and a couple of potty words there at the end as he becomes Pinky's cat-scratch pole. ("Excuse my language." Oh my gosh, I snorted!)
And Burger... Hmm. Not only would I not adopt Burger, I'm not sure I would venture within fifty feet of his cage. Bending steel with your mind is no problem when you're aligned with the Dark Side. Yikes.
