Behaviour and ecology

The Egyptian weasel is omnivorous and includes a significant amount (~50%) of vegetables and fruit in its diet, as well as waste human food and animals including rodents, chicks of poultry, rabbits, fish and insects. Their varied and opportunistic diet reflects their opportunistic synanthropic lifestyle. The males of the Egyptian weasel are solitary and highly territorial, marking the territorial boundaries with urine and faeces. The female may establish a territory within a male's territory within which she will make a nest in a cavity, wall crevice or rock pile. She defends this territory from other females.

Reproduction

During courtship, the pair trill and chatter and copulation can be quite a loud affair. After copulating she may remain with the male or the pair may separate and seek other mates. The females gives birth in her nest to a litter of between four and nine young, up to three times a year, if food supply allows.

Threats

At present, it is not considered threatened. Future potential threats are chemicals such as
