shut up for a hundred years with nothin' but cats to eat - Boo Radley in To Catch a Mockingbird

Dill said, “We’re askin’ him real politely to come out sometimes, and tell us what he does in there – we said we wouldn’t hurt him and we’d buy him an ice cream.”
“You all’ve gone crazy, he’ll kill us!”
Dill said, “It’s my idea. I figure if he’d come out and sit a spell with us he might feel better.”
“How do you know he don’t feel good?”
“Well how’d you feel if you’d been shut up for a hundred years with nothin’ but cats to eat? I bet he’s for a beard down to here – “

– Harper Lee

To Kill a Mockingbird, Chapter 5. Dill and Jem cook up a plan to drop a note into Boo Radley’s window with a fishing pole to get him to come out. Dill expresses some sympathy for Boo being shut up in his house for so long, while Scout is terrified Boo will kill them. The reclusive Boo is a victim of prejudice in Maycomb, and in the minds of children like Jem he is a figure of fear.
