I can guarantee my opinion here will be unpopular. That being said I think it should still be allowed even though I am a pet lover. It’s well known that we have a continually and rapidly growing problem with cat populations. Many cats ultimately become feral and they will also (as documented in New Zealand history) deplete and in some cases completely irradiate bird/lizard species. They are becoming a nuisance and this is one way of somewhat controlling it and it goes towards research so it’s not totally in vain.
