New findings reveal high-intensity sterilization of free roaming cats reduces populations with least preventable deaths

On July 26, 2019, the peer-reviewed open-access journal Frontiers in Veterinary Science published ACC&D's new paper, A Long-Term Lens: Cumulative Impacts of Free-Roaming Cat Management Strategy and Intensity on Preventable Cat Mortalities.

Frontiers News Graphic (2)Using computer modeling software to simulate the impacts associated with seven different management strategies for reducing cat populations, the authors evaluated the long-term impact of the different management strategies on deaths of cats and kittens during that reduction. The authors found that over a 10-year period, free-roaming cat populations managed using high-intensity Trap-Neuter-Return (TNR) not only reduced population sizes, but also that such populations experienced 31 times fewer preventable cat deaths over the same period, compared to taking no action.
