This system can work best with animals that have stable populations in which
territories are defended and for example one male controls all the females
and prevents them mating with other females and especially if all the mating
happens at one specific time of year. In such a case it can help to
sterilise that male. If that doesn't happen then you would need to sterilise
all or most of them. But do cats live in such systems..... I doubt it.
Sterilising one male cat in a population is pretty useless unless he is the
only one that all the girls desire. Sterilising all the females would be
great if we can find a way to do it.

for feral cats ???????
My understand was that sterilising a cat and releasing it (or better still,
sterilising it with some sort of dart) is much more efficient in medium to
long term population control than simply shooting it dead.
If you shoot it, another cat takes its place, with an overall effect on the
population of zero (that is, a total waste of time and effort).
But if you sterilise it and relese it, the cat continues defending its
territory and keeping others at bay for some years. This would result in a
much more effective population crash, I would think.
The more scientific or research-based contributors might like to comment
please.
