Trap–Neuter–Return is the only population control method
proven to reduce feral cat populations both immediately and
in the long-term. TNR is safe, cost-effective and strongly
supported by the public. If it is the concern of the larger
community to safeguard native wildlife from the predations
of feral cats, TNR is the best way to achieve that goal.
Numerous studies published in the Journal of the American
Veterinary Medical Association (JAVMA) back up these facts.
In contrast, other jurisdictions that for decades have practiced
trap-and-remove (kill) policies for feral cats find that, despite
increasing amounts of money and manpower, there are more
feral cats than ever.
