Maybe I should throw in owls. My mom and her sisters used to keep those. I remember Hooly, Laurel, Hardy, and there was a 4th one I can never remember.

I imagine he keeps pigeons and finches. The finches tend to steer clear of his squeeze box noises, but the pigeons know that's when the bread crumbs come out.

side note: my fellow narrator just screamed at me to read book two... my doctor friend better stay awesome and happy...
