Geographic Range
Black-footed cats are found in the savannas and grasslands of Botswana, Namibia, and
South Africa, as well as small parts of Angola, Zimbabwe, and possible Lesotho.
Habitat
Black-footed cats inhabit dry grasslands, savannas, and deserts of southern Africa.
The terrain they inhabit averages 100 to 500 mm of rainfall each year. They create
dens in burrows or abandoned termite mounds and also shelter temporarily in dense
thickets.

Physical Description
Black-footed cats are the smallest of African
Felis
species. The body is covered with light brown hair with black to dark brown spots
covering the back, sides, and stomach. Dark brown stripes similar to the spots appear
on the cheeks, front legs, haunches, and tail. In addition, the tip of the tail is
solid black (about twice the thickness as the stripes around the tail). The tail averages
150 to 200 mm, about half the body length. The bottom of the feet, which are often
visible due to their digitigrade style of walking, are black, giving this species
its common name. Males are slightly larger than females, averaging 1.93 kg, compared
to 1.3 kg for females.

- endothermic
- homoiothermic
- bilateral symmetry
- Sexual Dimorphism
- male larger
Reproduction
Black-footed cats are likely polygynous, as male territories overlap with up to 5
female ranges, while female ranges usually only overlap with one male home range.
Prior to mating, female urine-spraying increases to advertise her readiness to the
local male. Breeding is the only time that black-footed cats are found associating
with each other, except for females and their kittens. Males and females only associate
for 5 to 10 hours for mating.
- Mating System
- polygynous
Black-footed cats mate in the fall, in August and September, giving birth to young
in November to December in an underground den. Females may have multiple litters in
a year and young have been recorded in dens as late as February. Females average 1
to 3 offspring in each litter (1 to 2 is more typical). Gestation takes 59 to 68 days
and females give birth to young from 60 to 88 grams in weight. Young begin to venture
out of their den at 3 weeks old and are fully weaned at about 6 weeks old, when they
can begin to catch their own prey. Females become mature at 14 to 21 months old.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- viviparous
Female black-footed cats provide all post-copulation investment in offspring. Throughout
gestation and lactation, females invest heavily in their young.
Starting at about 3 weeks old, females begin to bring back live prey for their offspring
to practice catching prey with. During this time females bring back as much as 50%
of their catches in a night. Young may inherit territory from their mother.

Lifespan/Longevity
Little is known about life expectancy in black-Footed cats, but they are thought to
live up to 13 years, up to 15.6 years in captivity.
Behavior
Black-footed cats are solitary, only found with other individuals during breeding
or as a mother with dependent offspring. A predominantly nocturnal species, they are
rarely encountered and take shelter during the day in the burrows of other animals,
in dense thickets, or in caves or crevices.
- Key Behaviors
- cursorial
- terricolous
- nocturnal
- motile
- sedentary
- solitary
- territorial
Home Range
Male home ranges average 13 to 20 sq km, while female home ranges average 10 to 12
sq km. While overlap between sexes is common, and may make up as much as 50% of a
home range, individuals rarely spend significant time together (usually only for breeding).
A male's range may overlap with up to 5 separate female ranges. Territory is marked
via urine spraying in both sexes, not just at borders, but also at areas commonly
used by the individual. One study estimated population density at 0.17 per square
kilometer.
Communication and Perception
Because they are solitary, black-footed cats mostly communicate via scent marking,
mainly urine-spraying. Urine-spraying has two main uses; both as advertisement for
females to males pre-mating and for territory delineation. Mother and their young
communicate vocally. Females scent mark most during times when they are sexually receptive,
so it is thought to be mainly to attract male mates.
- Other Communication Modes
- pheromones
- scent marks
Food Habits
Black-footed cats eat a wide variety of small animals, 98% of which are mammals and
birds, mammals making up 72% and birds 26% of the diet. Animals weighing less than
40 g made up more than half of their prey base. Larger animals were mainly caught
during winter, when smaller prey was unavailable. These larger animals may be cached
for later use. The remaining 2% of prey items are made up of small amphibians, reptiles,
and invertebrates.

carnivore

- Foraging Behavior

Predation
Little is known about predation on this species. Unlike many
felids
, human predation on these cats is relatively rare. Their nocturnal habits, secretive
behavior, and spotted coats make it difficult to observe them.
- Anti-predator Adaptations
- cryptic
Ecosystem Roles
Black-footed cats are dominant predators of small mammals and birds in areas they
inhabit.
Economic Importance for Humans: Positive
Black-footed cats are important predators of small rodents, which can be crop or household pests or carry diseases.
- Positive Impacts
- controls pest population
Economic Importance for Humans: Negative
There are no adverse effects of black-footed cats on humans, although they may bite in self-defense, such as when harassed. Their prey are small and do not include human livestock.
Conservation Status
Black-footed cat populations are decreasing due to habitat degradation, threats from
hunters, and poisonous baits set for other predators. It is illegal to hunt black-footed
cats in Botswana and South Africa. Their range includes several national parks and
other wilderness areas, including Addo Elephant National Park, Karoo National Park,
Makgadikgadi Pans, and Mountain Zebra National Park. Black-footed cats seem to be
more rare than other small, African
felids
and populations seem to be fragmented. There is little known about their natural
history.

-
in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
