- “Mister Boots, why'd you have to do me that way?! I only wanted to grow you some tiger stripes, but that wasn't enough for you!”
- ― Oscar Calraca[src]
Mr. Boots was one of Oscar Calraca's cats that he had smuggled to Rapture. Oscar fed him ADAM and was forced to kill him when his addiction drove him to steal some of Oscar's ADAM. Oscar claimed he was just trying to grow him "tiger stripes," and that he would "grow claws in your [Mr. Boots'] honor."
