City rats loyal to their 'hoods, scientists discover
Date:5/27/2009

counterparts by a large waterway known as Jones Falls.

Within these hemispheres, rat families form smaller communities of about 11 city blocks. Each community is further divided into neighborhoods that span little more than the length of an average alley. To a city rat, that alley is home sweet home.

The findings suggest that while rats rarely migrate, neighborhood eradication efforts may backfire by encouraging the rodents to repopulate other areas and further spread disease. When you smell a rat, the researchers say, the best solution may be to tackle the problem on a much larger scale--perhaps by targeting entire families at once.

Rat race won.
