What
Do Cheetahs Eat
The answer to the question, "What do cheetahs eat" is fairly
simple.
The cheetah lives in an environment that suites the cheetah. What
suites the cheetah is sufficient space where he/she can use her skills.
Her skills are running at high speed, which allows her to catch prey
efficiently.
OK, the cheetah needs
large open and usually grassy spaces
both for
hunting and as a sufficiently large range. The great parks are perfect
examples, such the famous Serengeti.
The prey will come from the same environment. The environment is
a biotope, where species of plants and animals live together -
all adapted to that specific habitat.
The cheetah is effectively at the top
of the food chain as it runs too
fast for the animals below her
in the food chain. The cheetah uses
vision rather than scent and has a good success
rate perhaps higher than that of other big cats, but which is dependent
on the type of prey, the age and sex of the cheetah, the success of the
stalking and if hunting together or alone (see "how they catch prey" in
contents foe more). What is just below her in this habitat?

Thomson's gazelle - published under Wikipedia commons license.
A Thomson's gazelle is fast (about 50 mph) and can escape capture
apparently about 50% of the time. This is probably due to swerving
avoidance manoeuvres and tiring the cheetah, who as we know is
faster but has limited stamina. The cheetah is built for speed not
running efficiency (translated into stamina or endurance).
The gazelle is always present in areas where the cheetah lives and the
preferred weight of the prey is 20-50 kilogrammes.

Dik Dik is a shy elusive and small antelope found in eastern and south
western South Africa including Namibia where the largest population of
cheetah are found.
Impalas are wonderful athletes too. They are fantastic jumpers. They
can jump horizontally up to 10 meters (about 33 feet) and vertically
about 3 meters (about 9+ feet). They feed on the grassland and are in
the middle of the cheetah food chain. Impalas are the main prey in the
Kruger National Park accounting for 68% of all prey of the cheetah.
The Springbok is another fleet footed animal living in wide open
places. The Springbok has a top speed similar to the other antelopes
and the Impala at about 50 mph, 80 kph. They range in the south western
corner of South Africa which includes Namibia, the country with the
largest cheetah population. The Springbok makes up the bulk of the
cheetah's prey in areas of Botswana, South West Africa (Namibia).
The hare is a very fast runner and lives of the grass and shrubs. Uses
avoidance manoeuvres to evade the cheetah, zig zagging. This may tire
out the cheetah who can manoeuvre well but less well than a hare as she
is a lot bigger. A cheetahs partially retractable claws help in
manoeuvring. Hares tend to the prey of young cheetah hunting alone.
This is obviously an adult and cheetah usually hunt and kill the young
of the bigger animals. In fact prey is usually under 40 kilogrammes.
Although in the Sereneti, male groups of cheetah hunt 80 kilogram
wildebeest.
In addition cheetah prey is zebra (younger animals), rodents,
gamebirds Guineafowl.
What do cheetahs eat - Feeding
Ecology - Catching Prey
As mentioned, the cheetah's speed is best used in the open grassy
plains. They usually hunt in the daytime, but this is qualified by the
area that is their habitat, the heat of the day and the competition
from other big cats.
In the Sahara, where it is expectedly very hot, they hunt at night and
at dawn. While in the Serengeti they tend to fit their hunting in
around the hunting times of the lions and hyenas. In the Masai Mara,
the preferred times for hunting are between 7.30 am and 10 am in the
morning and 4.30 pm and 7.30 pm in the afternoon and evening.
The other top predators such as the lion and cheetah are more
aggressive than the cheetah and a threat. Cheetah keep a watch for
these animals from, for example, termite mounds (see top picture).
Watching can occupy 20% of the day (Masai Mara).
As is the case for the other big cats, the cheetah needs to get as
close as possible to the prey before attacking. The stalking segment is
important because if the prey are alerted and disperse during stalking
the hunt fails almost 75% of the time.
Where there is sufficient cover the cheetah might approach to 30 metres
before attacking. In areas of less cover the distance might be 200
metres. As is the case for the puma (for instance), if prey stands its
ground and doesn't run it is unlikely to be attacked (this is how a
cougar attack on a person is avoided in America). The fleeing of the
prey seems to be the stimulus for the cheetah to chase.
We are all aware of the cheetah's
speed in chasing down prey but this is limited to shortish
distances (400 yards). The top speed of the cheetah is 64 mph.
Having caught up with its prey the cheetah knocks it over or trips
it with the front paw, brings it down and strangles it, if the
prey is large. For smaller prey killing is accomplished by:
grabbing by the muzzle
bite to the neck
hares & young impalas can be killed by
biting
through the skull.
Cheetah will drag the kill into the shade of a bush if available and
rest. Cheetahs usually feed together without argument. When feeding
they watch for danger, particularly mothers with cubs. The cheetah may
eat about 10 kilogrammes at one sitting and eat fast. The time allowed
to spend at a kill undisturbed has an impact on how much is eaten.
Sometimes they scavenge (eat the kills of other animals). However,
there are few carcasses due to the efficient scavenging of other
animals such as the vulture and hyena.
It is thought that cheetahs lose between approximately 10 to 15% of
kills to, for example, the hyena (Kruger National Park - 14%).
