Coatis (Nasua nasua) are often found in the forest areas, but are also adaptable to small urban fragments. This may represent disorders and problems with living with human populations. Here, we showed the residents' perceptions, recorded through questionnaires, about the coati's approximation to urban areas, in the margin of a remnant fragment of Atlantic forest. Of interviewees, 66.23% did not attribute the coati's visitation to risk or considerable problems. Among those interviewed 80.52% offered food to the animals. They have also reported the coatis exploiting solid waste deposits. We reported a few isolated cases involving negative interactions between coatis and humans or domestic animals. Although we verified a positive outlook by the population to this interaction, there are several risks arising from the approach of these animals. We need to develop environmental education strategies to the population close to the forest fragment, as well as in-depth studies to verify and reduce such risks.
