The cat that played 'Kitty' was diagnosed with a serious kidney condition. Rather than replace the cat, it was decided to write the illness into the story. The real cat died shortly after this episode was filmed.
Chief Johnson refers to Kitty as her "little girl". It is the sole occasion whereby she acknowledges her gender.
Provenza talks about the time when he was still a Sergeant that Raydor wrote up a fellow officer who made a "misogynistic joke". He said the other person's name was George Andrews. This person would later come visit Provenza in Make Over (2009) and make a shocking announcement.
