Domestic cat preys reported by volunteers within the project Feral Cats

[Description of methods used for collection/generation of data] A citizen science questionnaire was created in the framework of Feral Cats Project in order to collect data on species captured by domestic cats. The project and a link to the questionnaire were advertised several times through online social networks (Facebook, Twitter, Instagram), mailing lists and Whatsapp groups and contacts. Volunteers were asked to attach pictures or videos about preys brought home by their own cats or to report occasional predation events performed by unowned cats such as cats living in a colony (either managed or not) or cats with unknown origin. The questionnaire was launched in autumn 2021 and kept open until the end of summer 2023. Although some volunteers reported a predation event without attaching a picture or a video, this dataset only includes those events with supporting files.
