starting a trap, neuter, and release program
building an animal shelter in a populated area
Explanation:
If you train animals to migrate, nothing guarantees that they won't end up coming back eventually, so there's no point in just putting them outside the town. If the problem is how they reproduce inside the town, you have to create spaces and policies that help to take care of the animals while achieving the goal of population control. Neutering and releasing is a good way of controlling the population; specially if combined with a shelter that can take care of the animals and also help with the neutering part of the plan.
