The Neighborhood Cats TNR Handbook is an A to Z guide for cat colony caretakers on all things Trap-Neuter-Return. Drawn from our years of hands-on work, it covers trapping, feeding, winter shelter, neighbor relations and veterinary care. Also discussed are more specialized topics like trapping hard-to-catch cats and what to do with nursing mothers and their kittens. "The hands-on expertise of Neighborhood Cats' staff, as well as the group's involvement with caretakers around the world, makes this the most comprehensive and up-to-the-minute resource for educating caretakers on all aspects of colony management." (Animal Sheltering Magazine, Sept/Oct 2013.)
With Return-to-Field (RTF), community cats impounded by shelters are spayed or neutered and returned to their original locations instead of being euthanized or rehomed. The now second edition of the Return-to-Field Handbook, a collaboration of Neighborhood Cats, Humane World for Animals and Alley Cat Advocates, provides detailed guidance on all steps of the RTF process. These include community messaging, gathering information at intake, assessing eligibility, staffing, housing, veterinary care, performing returns, data collection and more. If you're looking to start a RTF program or improve an existing one, read this book first! Available for free download.

Topics include targeted TNR, return-to-field, grassroots mobilization and integrating these approaches. Download for free or purchase a print copy on Amazon.
