Feral cats (Felis catus) are listed as one of the '100 world's worst invasive alien species'. There are as many as 70-100 million feral cats in the United States as well as an estimated 117-157 million domestic indoor and outdoor cats. Management efforts include a nonlethal feeding and sterilization program known as "trap-neuter-release" (TNR) where cats are surgically sterilized and returned to the environment. Population size and structure, immigration rates, spay/neuter rates, and data on spatial use all play a role in whether TNR is a viable management option. This study focuses on population structure and spatial use. To infer the population structure of a population of campus free-roaming cats at the individual level I used pairwise maximum likelihood estimates of relatedness and relationship category (unrelated, half-sib, full-sib, parent-offspring). Home range and movement patterns of domestic free-roaming indoor/outdoor cats were estimated with 100% and 50% adaptive local convex hull and 100% minimum convex polygon for comparison with previous studies. No differences in home range were found between sex, age, and season.
