Analysis of the impact of trap-neuter-return programs on populations of feral cats

摘要: Objective—To evaluate 2 county trap-neuter-return (TNR) programs for feral cat population management via mathematical modeling. Design—Theoretical model. Animals—Feral cats assessed from 1992 to 2003 in San Diego County, California (n = 14,452), and 1998 2004 Alachua Florida (11,822). Procedure—Data were analyzed with a Ricker model describe dynamics of the modifications that occurred as result TNR programs. Results—In both counties, results analyses did not indicate consistent reduction per capita growth, multiplier, or proportion female pregnant. Conclusions Clinical Relevance—Success use can be monitored an easily collected set data statistical facilitated by modeling techniques. Results may used suggest possible future monitoring modification programs, which could resu...
