Where do people come up with this stuff?

Sources:

• (left box)  The 17 best cities for dogs.  (Estately Blog, 5/13/2013)
• (right box) Madison City Ordinances chapter 23

The following words do not appear anywhere in the Madison City Ordinances:

• bait/baiting (as applied to squirrels; 2 mentions of 'bait shops')
• chatter/chattering
• squirrel/squirrels
• swish/swishing

Ditto for chapter 47 ("Animal Control") of the Dane County ordinances.
