“…In the literature we have a record of the predation of other snakes by domestic cats (Santos et al 2011;Assis et al 2022). The predation of the Linnaeus Sipo was opportunistic, it was preying on a bird's nest when it was preyed on by the feline.…”

Domestic cats (Felis catus) are listed among the 100 worst invasive species with the most impact on the environment and conservation, threatening a variety of native and even threatened animal species. Data indicate that they are responsible for the extinction of 33 species of birds. The objective of this work is to describe the predation of native and exotic species of fauna by a wildered domestic feline, specifically to bring data from the preyed species and data from the existing bibliographic of the predation by felines in the country. This is an observatory study, where the prey slaughtered and brought by the community cat were cataloged and listed over a period of 30 days in the summer of 2020. The animal brought the prey to the feeding place and dormitory, in front of one of the houses in which it received care. The study site is in the Camobi neighborhood, in the municipality of Santa Maria, state of Rio Grande do Sul, Brazil. Geographical location 29°41'47.9"S 53°44'20.4"W. This is the first report of the predation of two bird species (Falco sparverius and Leptotila verreauxi) and two Squamatas (Tupinambis and Philodryas olfersii) in Brazil. The results obtained may contribute to reduce the lack of information regarding the impacts of Felis catus and support the need to implement management policies and environmental education, aiming to combat the abandonment of domestic animals and encourage practices such as castration and responsible adoption of animals.

“…The specific effect of owned or semi‐owned domestic cats is less known (compared to feral cats) but there is growing interest in quantifying their effect on mainland wildlife (Assis et al, 2023; Brickner‐Braun et al, 2007; Loss & Marra, 2017; Mella‐Mendez et al, 2022; Mori et al, 2019; Woods et al, 2003). Based on the precautionary principle (Calver et al, 2011), many researchers call for better management of domestic cats to limit their effects on wildlife (Crowley et al, 2019) especially because owners can directly implement them.…”

Domestic cats' varying home range sizes are connected to their impact on wildlife. Most of the previous studies suffered from lacking causality or small sample sizes. To overcome these limitations, we conducted a comprehensive study involving 55 owned domestic cats in a French suburban area where each cat was monitored during one or nine sessions over 5 years and all four seasons. We tracked the cats using GPS technology while controlling for the device used for monitoring, climatic conditions, environmental changes, and their degree of roaming. Using linear mixed‐effect models, we found that age and sex significantly predict home range size. Younger cats tend to have larger home ranges and male cats have larger home ranges compared to females. We also found that the device used during the monitoring influenced the size of the home range. Surprisingly, climatic conditions, surrounding environment and degree of roaming had no significant impact. When considering our models, most of the variability in home range size was due to random effects that accounted for the identity of cats which were monitored one or more times. Therefore, a deeper understanding of intrinsic and extrinsic factors influencing home range size in domestic cats is crucial. This includes investigating individual behavior, breed‐specific traits, and the role of owner care but also reassessing management solutions for reducing cat roaming and not only focusing on restrictive ones. Identifying these factors will enable the development of more effective management.

“…The presence of dogs affects at least 37 native species in Brazilian PAs, some of which listed in the IUCN Red List(Lessa et al 2016). Cats are a prominent contributor to global extinctions (IPBES 2023), known for preying on at least 48 vertebrate species in Brazil(Assis et al 2023). Population control and eradication measures of such pets pose a signi cant challenge to biodiversity conservation efforts due to strong bonds with humans.…”

The number of invasive non-native species (INNS) has been increasing in Brazilian protected areas (PAs) in the last decades, even though Brazil is close to reaching the Global Biodiversity Framework Target of having at least 30% of the territory conserved in PAs. The main aim of our study is to identify spatial patterns and factors that describe the number of INNS in federal and state protected areas in Brazil. We integrated and standardized three sources of occurrences of INNS in federal and state PAs with a new database built for this study based on occurrences reported in 424 management plans (MP). A generalized linear model was used to assess the factors that best describe the number of INNS in PA using biome, year of PA creation, PA area, PA group, and PA category as fixed effects. We compiled 5,631 occurrences of 150 invasive animals, 179 invasive plants, four ferns, three protists, one alga, and one bryophyte. Protected areas with the highest number of INNS are concentrated along the coast, in the Atlantic Forest biome, especially in the south and southeast of Brazil. Biome, PA category, and PA year of creation were the most important variables in the model. We expect our results to show the magnitude of biological invasions in Brazilian PAs and we provide baseline data and recommendations to be used as reference for the development of policies and management actions at regional and local levels, thus contributing to the achievement of KMGBF targets.
