OBJECTIVE To evaluate the efficacy of trap-neuter-return and trap-euthanatize management strategies for controlling urban free-roaming cat populations by use of matrix population models. DESIGN Prospective study. SAMPLE POPULATION Estimates of free-roaming cat populations in urban environments. PROCEDURE Data from the literature describing the biology of free-roaming cat populations in urban environments were gathered. A matrix population model was developed with a range of high and low…

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

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.

Simulating Free-Roaming Cat Population Management Options in Open Demographic Environments

A stochastic demographic simulation approach is used to evaluate removal, permanent sterilization, and two postulated methods of temporary contraception for FRC population management and account for the realities of FRC dispersal and owned cat abandonment.

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.

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

Estimation of effectiveness of three methods of feral cat population control by use of a simulation model.

An individual-based stochastic simulation model was developed to evaluate the effectiveness of trap-neuter-release, lethal control, and trap-vasectomy-hysterectomy-release in decreasing the size of feral cat populations and concluded TVHR should be preferred over TNR for management of feral cats if decrease in population size is the goal.

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.

An Evaluation of Feral Cat Management Options Using a Decision Analysis Network

The feral domestic cat (Felis catus) is a predatory invasive species with documented negative effects on native wildlife. The issue of appropriate and acceptable feral cat management is a matter of

Guidance for management of free-roaming community cats: a bioeconomic analysis

Simulations suggested that cost-effective reduction of FRC numbers required sufficient management intensity, regardless of management approach, and greatly improved when cat abandonment was minimized, and suggested that trap–neuter–return was a viable and potentially more cost- effective approach if performed at higher intensities over a sufficient duration.

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

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.

Predicting feral cat-reduction targets and costs on large islands using stochastic population models

Feral cats are one of the most destructive invasive predators worldwide. Due to the high risk of pushing native species to extinction in Australia, density-reduction or eradication campaigns can



Evaluation of the effect of a long-term trap-neuter-return and adoption program on a free-roaming cat population.

A comprehensive long-term program of neutering followed by adoption or return to the resident colony can result in reduction of free-roaming cat populations in urban areas.

Characteristics of free-roaming cats evaluated in a trap-neuter-return program.

Neutering programs for free-roaming cats should include preparations to perform more spays than castrations, as Typically, almost half of the female cats trapped during spring will be pregnant and care should be taken to differentiate previous castration from retained testicles.

Feline population dynamics: a study of the Manhattan, Kansas, feline population.

Analysis of the age-specific birth and survival rates and the age distribution in the pet population of cats in Manhattan, Kansas, revealed that the rate of population change (lambda) was about 1.18.

Evaluating the Effectiveness of Predator Control: the Non‐Native Red Fox as a Case Study

The approach indicated that predator control was effective in the short term, but for longer-term success it may be necessary to redirect efforts to control juvenile and immigrant foxes.

Canine population dynamics: a study of the Manhattan, Kansas, canine population.

Analysis of the age distribution in the pet population of dogs in the community of Manhattan, Kansas from 1968 to 1979 revealed that the distribution was stationary and the rate of population change

Demographic variation and population viability in Gentianella campestris: effects of grassland management and environmental stochasticity

Traditional grassland management is more favourable for G. campestris than the methods that prevail in Scandinavia today, and this indicates a serious conservation problem, because grazing has replaced traditional management in many of the remaining semi-natural grasslands throughout Europe.

Characteristics of free-roaming cats and their caretakers.

Recognition of the human-animal bond that exists between caretakers and the feral cats they feed may facilitate the development of effective control programs for feral cat populations.

Study of the feline and canine populations in the greater Las Vegas area.

Analysis of household dogs and cats, based on age-distribution data and on age-specific birth and survival rates, as well as on pet source, indicated that the dog and cat populations are stable and

Stochastic matrix models for conservation and management: A comparative review of methods

Stochastic matrix models are frequently used by conservation biologists to measure the viability of species and to explore various management actions. Models are typically parameterized using two or
