I know it sounds like a strange topic, but since the topic of which handgun caliber for bears keeps popping up about once a month in the handguns forum, I thought proportionally sensible to discuss which rifle calibers are best for which chores commonly left to handguns, such as CCW defense, plinking rats out of the attic, etc. I'm thinking...
.17 Rem bolt gun for very small rodents at close to mid-ranges - good accuracy is needed to pop the little 'uns.
Marlin .22 WRM smoothbore "garden gun" would also be good for small rodents or stationary birds.
HK MP5 or MP5/10 in a shoulder sling under a trench coat for concealed carry would be about optimum for a concealed rifle/carbine.
