Recidivism is a real problem for some shelter cats. Quilty, a seven-year-old domestic shorthair, was born in the Friends For Life Animal Rescue and Adoption Organization (FFL), a Houston-area animal shelter. Named after Claire Quilty in Vladimir Nabokov's "Lolita," Quilty was recently returned to the shelter he was born in after his adopter moved and couldn't bring him along. He immediately started causing trouble.

Quilty knows how to open doors, and liberated the other captive cats in the shelter like some kind of feline Simon Bolivar. "Quilty loves to let cats out of the senior room. Repeatedly, several times a day," the shelter wrote on Facebook. "Quilty will not be contained. And he has no shame."

Quilty was caught and sentenced solitary confinement (i.e. left to sit behind a glass door) for the jail breaks, looking adorably sad yet showing no remorse.
