Abstract:  Many jurisdictions have adopted programs to manage feral cats by trap–neuter–return (TNR), in which cats are trapped and sterilized, then returned to the environment to be fed and cared for by volunteer caretakers. Most conservation biologists probably do not realize the extent and growth of this practice and that the goal of some leading TNR advocates is that cats ultimately be recognized and treated as “protected wildlife.” We compared the arguments put forth in support of TNR by… 

Rabies Prevention and Management of Cats in the Context of Trap–Neuter–Vaccinate–Release Programmes

TNVR programmes are not effective methods for reducing public health concerns or for controlling feral cat populations, and responsible pet ownership, universal rabies vaccination of pets and removal of strays remain integral components to control rabies and other diseases.

How Effective and Humane is Trap-Neuter-Release (TNR) for Feral Cats?

The pros and cons of trap-neuter-release programs for reducing feral cat populations without euthanasia are discussed in this 8-page fact sheet published by the UF/IFAS Department of Wildlife Ecology and Conservation.

The purpose of this review is to describe for a veterinary audience how to facilitate more effective sterilization-based management of outdoor cats, using a combination of theoretical knowledge derived from population modeling and empirical knowledgederived from population monitoring.

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

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.

Effects of sterilization on movements of feral cats at a wildland–urban interface

Abstract Trap–neuter–release (TNR) programs, in which feral cats are sterilized and fed in unconfined colonies, have been advocated as a humane and effective way to reduce the impacts of feral cats

A review of trap-neuter-return ( TNR ) for the management of unowned cats

  • Political Science

The management of unowned, stray or feral cats is an extremely complex and emotive issue. Trapneuter-return (TNR) is one method promoted, primarily in the United States, as a humane alternative to

Free-ranging domestic cat abundance and sterilization percentage following five years of a trap–neuter–return program

Assessment of the effectiveness of a TNR program initiated in 2013 in Stillwater, Oklahoma, USA and changes in cat abundance and the percentage of ear-tipped (i.e. sterilized) individuals between 2014 and 2018 suggest that TNR conducted at its current intensity is unlikely to reduce Stillwater's cat population.

Opinions from the Front Lines of Cat Colony Management Conflict

Conservation community can manage conflicts more productively by bringing CCCs into the process of defining data collection methods, defining study/management locations, and identifying common goals related to caring for animals.

Identifying people’s most preferred management technique for feral cats in Hawaii

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

Although TNR advocates and opponents share a common belief that neutering programs and education of cat owners and advocates are paramount to effectively dealing with unconfined cats, they have areas of philosophic and practical disagreement.

Analysis of the impact of trap-neuter-return programs on populations of feral cats.

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.

The welfare of feral cats and wildlife.

In my opinion, attempting to maintain cats in colonies only compounds the problem by causing massive killing and crippling of native wildlife, jeopardizing biodiversity, undermining traditional animal control, enabling irresponsible people to abandon cats, and sending mixed messages about the veterinary profession’s commitment to serve the welfare of all species.

Veterinarians should join hands on a nationwide campaign to educate the public as to the importance of keeping their cats confined, and factual, objective information presented in a similar fashion can advise as to why cats should be confined for the sake of the cat, the environment, other animals, and the public.

The Effects of Implementing a Feral Cat Spay/Neuter Program in a Florida County Animal Control Service

Changing from a policy of euthanasia of feral cats to support for trap-neuter-return did not result in an increase in the number of complaints or cat impoundments, and the percentage of impounded cats euthanized decreased, andThe percentage adopted increased.

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

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.

Humane strategies for controlling feral cat populations.

Debate about the true impact of free-roaming cats on the envi-ronment, on feline welfare, and as a reservoir of feline and zoonotic diseases is ongoing, often emotional, andfueled largely by a lack of sound scientific data on which to base credible conclusions.
