Sebastian was a cat that attached himself to our family. I associate Sebastian with the song "The Cat Came Back" because my father would sing that song and it always seemed to be referring to that cat, because my mother didn't like cats but somehow Sebestian managed to ingraciate himself into her good graces nevertheless.
