That's how I'd do it. Yuck! Give me furry critters any day, I can handle mice and rats, no problem.
I don't mind mice--used to raise hamsters and gerbils. Rats creep me out, though, 'cause of the disease risk I guess, and also because when I was little my Dad told me a story about a big one my Grandpa had to kill in the barn once--big as a cat and mean, so my Grandpa had to stick a pitchfork in it.
