Background information and definitions
Collar-mounted devices, such as bells, alarms, and lights may reduce predation by making cats more conspicuous. Cats equipped with collar-mounted bells, sonic devices and a ‘pounce protector bib’ have been found to capture fewer mammals than without the devices (Nelson et al. 2005, Calver et al. 2007). Bats were among the mammals caught, but numbers captured with and without the devices were not reported.
