The domestic cat (Felis silvestris catus) is indicated as a threat to several native species in different regions where they occur, especially seabirds in insular environments. In this study, we present the results obtained through fecal analysis and identification of the remains of prey killed by domestic cats in a fishing village in an insular area of the Brazilian Atlantic Forest. Although several species of seabirds use the island either as a migratory route, residence, or for nesting, we did not detect their presence among the identified items. However, other species of birds, mainly Passeriformes, were found. This corresponded to less than 10% of the total of items identified as predated by domestic cats during the sampling period. We emphasize the importance of carrying out new studies, as well as evaluating measures to identify more sensitive species and preventing potential impacts caused by felines in forest remnants in Neotropical regions.
