It seems they have something in common with many of us Baltimoreans. They like to live near to where they were born and raised. They might move a block or two away, if need be for food or because the neighborhood bully forced them out.

But mostly, they like to stick close to home.

If you'd like to help cut down on the population, try putting your trash in a can with a lid -- which is actually the law for which tickets are now being written -- or at least only put the bag out on trash day.
