Dogs and cats with free access to protected areas can cause problems considered of great importance to wildlife conservation. This cenario occurs in the city of São Miguel Arcanjo (São Paulo State, Brazil), located near the Carlos Botelho State Park (CBSP). The fact that cats and dogs enter protected areas has an impact on human health and on the conservation of local biodiversity. When domestic animals interact with wild animals of unknown health status, the transmission of zoonoses is facilitated and when they pray wild animals and mark territory, they can negatively affect the population dynamics of wild species. In addition, free-ranging cats and dogs are constantly exposed to several factors that affect their well-being. Therefore, population management of dogs and cats living in places close to these protected areas is urgently needed,  so it will be possible to minimize the interaction with wildlife and consequently improve the quality of life of wild animals, the welfare of domestic animals and the health of people linving in the area. Population management based on the context, beliefs and knowledge of local residents tend to be more effecient and resource saving. Thus, based on the perception and attitudes of the population for the elaboration and application of a proposal related to health education, prevention of zoonoses, preservation of biodiversity and population control of dogs and cats, this research project aims to supply a demand and solve the problem of the lack of public policies focused on these issues in the region.
