The Alberta mountain town of Canmore has begun trapping and killing feral rabbits.

Canmore spokeswoman Sally Caudill says she doesn't know how many rabbits have been humanely killed, but the trapping started in mid-October. What to do about the picturesque community's out-of-control rabbit population has been controversial.

A mass extermination was avoided last year when a group called Earth Animal Rescue Society came forward and managed to find sanctuary for 213 animals. 

At least 187 rabbits were neutered last spring, avoiding their original fate of being euthanized.

The society hasn't been able to find any sanctuary space this time around, although organizer Susan Vickery is hopeful something might come through.

The rabbits were originally pets, but were released in the 1990s and started doing what bunnies do best — multiplying.
