Perhaps we could just give them birth control. Let them die out on their own. We need to develop highly targeted birth control methods like that. Eradicate wild hogs as well.
That (birth control ) is being done in places here...people pay to have ferals rounded up, “fixed,” vaccinated, then returned to their home area where they keep the rodent population down
In my town, and in many others, sterilizing stray cats is being tried. The theory is that, if you just kill feral cats, there will always be another one to take its place. But a sterilized cat would prevent other males from entering its territory....and not reproduce.
We’ll see if it works.
There are trap-neuter-release (TNR) programs popping up all over the country, and charities that educate people and help them set up TNR programs in their neighborhoods. TNR is a much more humane option than trying to kill off the stray cats.
Mind you, the TNR programs are only for cats, not feral hogs. I strongly suggest just shooting the hogs.
