In fact, I once saved a youngish Oriental cockroach (Blattella orientalis) that arrived at my work in a box of t-shirts from Pennsylvania, I think. (Yeah, I think I've mentioned this before...) I took him (for he was a male cockroach) in, fed him (he liked bagels, pizza, muffins, tacos), and built him a home out of plastic cups and popsickle sticks. I never could think of a good name for him, though I started calling him "Stumpy" when he got old and lost a leg or two. Got to see him moult, drink water from my hand, scurry, all that. I had him for one and a half magical years before he died in 2000, at age two+... :(
