Uh oh.
Does Ptarmy live in Chicago?

You may not know this but I have been a long time proponent to use the garment industry to use rat skin or hide.
Rats have a hide that is water proof and stronger then the other hides we use in garments.

Take the city's over run with rats, put a $.50 cent bounty on the rats turned in to the city. People with a rat problem will find a way to catch the vermin and make money doing it.
The city then sells the hides to the Military or garment industry and it becomes a win-win to rid the rats from the city's and produce strong hide for clothing.
Put a bounty on rats and and use the hide for strong weather proof material. The meat from the rats will go into pet food or hog feed.
If I were to go to say NYC and offer a street gang a bounty on Rats, within a week I would have 3-4 if not more Dumpsters filled with them.
What about the teeth and bones, great fertilizer for crops.
So for say 10 years this goes on, all big city's have the hunt for the rats. Then some one in Government will place them on the endangered species list.
What is the problem with rats gone from our citys----easy , less disease---not good for the hospitals that see 30 rat bites a month on baby's, less injudicious diseases to hire more doctors to combat and need government help.
Then Pita steps in and we have a mess on our hands.
