Button had kittens. Shelly attempted to throw the kittens out onto the street, but they were taken in by Jooseppi, who happened to be running another protest in front of the Ossified Egg.
Button went away, and received no legal or financial support from the Bundts ever again. Shelly immediately adopted a new orphan kitten to train in the ways of prudishness and pomp.
Button received a reduced sentence of 5 years, served 2, and walked out of the prison's gates and into the paws of Flynn. They went on to have multiple litters of alley kittens, and their Family prospered.
