Catch and release isn't really recommended. They tend to learn better than to get caught by the same traps again.

After one particularly bountiful summer many folks, here at work, rigged up various non lethal traps.

One trap involved a teeter totter affair that dumped into a 5 gallon bucket. After several demonstrations, using the same mice. The mice started teaming up and taking turns. One would act as a counter weight so the first could run out and snatch the bait without being dumped in the bucket.
