A radio-collared, female black-footed cat (Felis nigripes) was followe
d for a total period of 575 hours, over seven observation periods span
ning 18 months, in the Kimberley region of the Northern Cape Province,
South Africa. Data on reproduction and scent marking were collected b
y direct observation. The predominant form of scent marking was urine-
spraying, the frequency of which fluctuated during the year and seemed
to be related to changes in the reproductive cycle. Marking frequency
increased dramatically approximately one and a half months before mat
ing, and conception of the first litter of the breeding season occurre
d at a low frequency during pregnancy, and was entirely absent when th
e cat was rearing young. This strongly indicates a primary function in
the advertisement of female reproductive condition, although an addit
ional role in the maintenance of social spacing is suggested. Scent ma
rks were not restricted to the borders of the animal's range, but corr
esponded to those areas used most intensely during the year.
