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.
