Increasing free-ranging cat populations are a cause of concern for wildlife management and biodiversity conservation. Cats carry and transmit multiple diseases, annually depredate billions of birds and mammals in the mainland United States, and have caused extinctions and declines of wildlife populations worldwide. Trap–neuter–return (TNR) efforts, which entail trapping, sterilizing and releasing unowned free-ranging cats with the goal of reducing populations, have been implemented globally… 

Cats Are Not Fish: A Ricker Model Fails to Account for Key Aspects of Trap–Neuter–Return Programs

TLDR
A Ricker model, originally developed for application in the management of fisheries, was used to assess the effectiveness of trap–neuter–return (TNR) programs for managing free-roaming domestic cat populations, and it was revealed that it cannot account for some key aspects of typical TNR programs, and the wild population swings it predicts do not correspond to the relative stability of free- roaming cat populations.

Evaluation of euthanasia and trap–neuter–return (TNR) programs in managing free-roaming cat populations

TLDR
It is indicated that immigration must be prevented and high treatment rates implemented to reduce free-roaming cat populations and that euthanasia required higher treatment effort than TNR.

Costs and Benefits of Trap‐Neuter‐Release and Euthanasia for Removal of Urban Cats in Oahu, Hawaii

TLDR
Results of sensitivity analyses suggested trap‐neuter‐release programs that employ volunteers are still less cost‐effective than trap and euthanize Programs that employ paid professionals and that trap‐NEuter‐ release was only effective when the total number of colony cats in an area was below 1000.

Population impacts of free‐ranging domestic cats on mainland vertebrates

TLDR
Policy discussions should shift from requiring “proof of impact” to a precautionary approach that emphasizes evidence-driven management to reduce further impacts from outdoor cats.

Decrease in Population and Increase in Welfare of Community Cats in a Twenty-Three Year Trap-Neuter-Return Program in Key Largo, FL: The ORCAT Program

TLDR
A trap-neuter-return program operating for over two decades achieved a decrease in population and an increase in population welfare as measured by increased average age of population and decreased retrovirus prevalence.

Free-ranging domestic cats (Felis catus) on public lands: estimating density, activity, and diet in the Florida Keys

TLDR
Evidence is provided that cat groups within a population move different distances, exhibit different activity patterns, and that individuals consume wildlife at different rates, which all have implications for managing this invasive predator.

Estimating free-roaming cat populations and the effects of one year Trap-Neuter-Return management effort in a highly urban area

Free-roaming cat populations are increasing in urban areas around the world. Management strategies remain controversial, as attempts to rapidly minimize the impact of cats may conflict with finding

The impact of free-ranging domestic cats on wildlife of the United States.

TLDR
It is suggested that free-ranging cats cause substantially greater wildlife mortality than previously thought and are likely the single greatest source of anthropogenic mortality for US birds and mammals.

Feral cats (Felis catus) are abundant in many parts of the world and pose a threat to native wildlife. Human-wildlife conflicts regarding how feral cats should be managed have increased recently. In

Use of matrix population models to estimate the efficacy of euthanasia versus trap-neuter-return for management of free-roaming cats.

TLDR
Free-roaming cat populations have a high intrinsic growth rate, and euthanasia is estimated to be more effective at reducing cat populations than trap-neuter-return programs.

TLDR
Success of feral cat management programs that use TNR can be monitored with an easily collected set of data and statistical analyses facilitated by population modeling techniques.
