I assume you are speaking of real rats, not the democRAT kind. Did they have cholesterol problems?
REAL rats as large as house cats.
They unloaded the grain boats right there near the factory.
There were alot of old abandoned grain silos around there. It was not a pretty part of town. After seeing where they made cheerios , I did not eat them for years.
I tried not to get to close enough to those rats to check their cholesterol. However, they did look well fed.
We would bring the burnt cheerios home for our horses. A friend of mine raised three pigs on nothing but cheerios.
