>>If not, can we release a rat specific poison or is that impossible without harming the entire ecosystem? Animals bunch around places where there is food. And the hard part is if you have food these animals generally multiply well enough to eat that food. In India its common to see street dogs, because food littering. Some times they take away the dogs, but they repopulate again in months/years. And in places where they don't litter you will see there are no dogs.
