LOS ANGELES, Dec. 29 (UPI) -- The Los Angeles Police Department teamed up with a local animal welfare group to use colonies of feral cats to control rodent populations.

The Working Cats program of the Los Angeles-based Voice for Animals placed feral cats in several area police stations with mouse and rat problems.

The method worked in the past when feral cats chased the rats out of a parking lot for the Wilshire Division of the LAPD six years ago.

"Once we got the cats, problem solved," Police Cmdr. Kirk Albanese told Saturday's Los Angeles Times. "I was almost an immediate believer."

The scent of the felines, as opposed to the killing of rodents, is the most important feature of rodent control by feral cat colonies.
