Abstract
As the number of feral cats continues to increase, land managers, public health officials, and private citizens are voicing concerns about how to address the nuisance and public health impacts, as well as animal welfare concerns, that feral cats create. Trap-neuter-release programs aimed at reducing feral cat populations without euthanasia are gaining popularity in the United States. But do they work? Authors Mark Hostetler, Samantha M. Wisely, Steve Johnson, Elizabeth F. Pienaar, and Martin Main discuss the pros and cons of trap-neuter-release programs in this 8-page fact sheet published by the UF/IFAS Department of Wildlife Ecology and Conservation.
