Essay: A review of current methods used to control free-roaming cat populations and their effects on feline welfare

 

Introduction

After recent debate over the best method for reducing free-roaming cat populations (Robertson, 2008), the general consensus is that methods should be effective, practical and, most of all, humane. Free-roaming cats present a variety of issues, such as the spread of zoonotic diseases, wildlife predation, threats to native species, spread of disease to pet cats, and public nuisance (Schmidt et al., 2009). However, cat welfare is also a critical issue, especially inhumane methods of control used on the animals, and alarmingly high rates of disease, ill health and abuse among colonies (Lepczyk et al., 2010; Farnworth et al., 2011). This review assesses different methods of control, with due consideration of cat welfare.

Nonsurgical fertility control for managing free-roaming dog populations: a review of products and criteria for field applications

About 75 per cent of dogs worldwide are free to roam and reproduce, thus creating locally overabundant populations. Problems caused by roaming dogs include diseases transmitted to livestock and humans, predation on livestock, attacks on humans, road traffic accidents, and nuisance behavior.

Nonsurgical fertility control is increasingly advocated as more cost-effective than surgical sterilization to manage dog populations and their impact.

The aims of this review were to 1) analyze trends in numbers of scientific publications on nonsurgical fertility control for dogs; 2) illustrate the spectrum of fertility inhibitors available for dogs; 3) examine how differences between confined and free-roaming dogs might affect the choice of fertility inhibitors to be used in dog population management; and 4) provide a framework of criteria to guide decisions regarding the use of nonsurgical fertility controlĀ for dog population management.
