Abstract

Feral cats have been identified as a major threat to Australian wildlife; however, their impacts on the critically endangered Leadbeater's possum (Gymobelideus leadbeateri) are unknown. Here, we describe camera trap observations of a feral cat hunting at nest boxes occupied by Leadbeater's possum. Seven feral cats were subsequently captured within the surrounding area: two had Leadbeater's possum remains in their stomachs. The prevalence of cat predation on this species, particularly at nest boxes, and how this can be mitigated warrants further investigation.
