Substantial and sustained reductions in community cat populations associated with trap–neuter–return (TNR) programs have been documented in a variety of locations, including in the northeastern, midwestern, and southeastern United States, as well as Australia. The present study adds to this growing body of evidence by examining the impact of a TNR program on a population of community cats living on a two-mile section of a pedestrian trail adjacent to the San Francisco Bay. An initial population of 175 cats declined by 99.4% over the 16-year program period. Of the 258 total cats enrolled between 2004 and 2020, only one remained at the end of the program period. The results of the present study corroborate previous research findings.
