Well, coyotes would take care of the feral cats, but they wouldn’t bother with the rats and I doubt they could catch the weasels.
Snakes could kill the rats, but the weasels would eat the snakes... what is good at catching weasels? Some kind of raptor maybe?
Napalm.
“what is good at catching weasels?”
Certainly not the FBI.
See my post at #47...mobilize humans!
