Quick Facts:
If cats are removed from their outdoor home, it creates a territorial opening, or vacuum, that will not remain empty.
Removing cats from an area may cause a temporary decrease in the cat population, but more cats WILL take their place–and it won’t take long.
This phenomenon is known in conservation studies as the Vacuum Effect. The Vacuum Effect has been observed in many species, not just cats.
Catching and removing (or killing) cats is therefore futile. It is an expensive, deadly cycle which yields no long-term benefits.
Trap-Neuter-Return (TNR) is the only way to stabilize cat populations. It is the humane, effective approach to community cats and is sound public policy.
