I agree with your post... However, chemical sterilization via food can be tailored to cover both males and females... But for some reason those in power won’t do it....
I guess because someone’s pedigree animal might eat it or ? ... But it would work.
In Texas there has been a big surge in coyote hunting - I haven’t seen a pack of coyotes on my land in almost two years (used to be nightly in summer). but the feral cat population has increased...
Although it is not really a pleasant thought, I prefer natural methods of population control... predator/prey.
But alas the coyote population was getting out of control too... Chemical sterilization also works for coyotes. But it is not done - likely because of the same reason cited above.
Has nothing to do with "pedigreed" animals. Anyone whose "pedigreed" pet is wandering around loose AND not spayed/neutered, is obviously not concerned about its breeding potential. The problem is that all sorts of wildlife would also be susceptible, potentially devastating certain species and/or upsetting the ecosystem.
