Description

The serval is a medium sized cat, measuring 59 to 92 cm (23.2 to 36.2 in) in head-body length, with a relatively short, 20 to 38 cm (7.9 to 15 in) tail, and a shoulder height of about 54 to 66 cm (21.3 to 26 in). Weight ranges from about 7 to 12 kg (15.4 to 26.5 lb) in females, and from 9 to 18 kg (19.8 to 39.7 lb) in males.

It is a strong yet slender animal, with long legs and a fairly short tail. The head is small in relation to the body, and the tall, oval ears are set close together. The pattern of the fur

Fur is a synonym for hair, used more in reference to non-human animals, usually mammals; particularly those with extensives body hair coverage. The term is sometimes used to refer to the body hair of an animal as a complete coat, also known as the "pelage". Fur is also used to refer to animal...

White servals have never been documented in the wild and only four have been documented in captivity. One was born and died at the age of 2 weeks in Canada in the early 1990s. The other three, all males, were born at Wildlife on Easy Street in 1997 and 1999.

Servals have the longest legs of any cat, relative to their body size. Most of this increase in length is due to the greatly elongated metatarsal bones in the feet. The toes are also elongated, and unusually mobile, helping the animal to capture partially concealed prey. Another distinctive feature of the serval is the presence of large ears and auditory bulla
Auditory bulla

, and springbok, though over 90% of the serval's prey weighs less than 200 g (7 oz). The serval eats very quickly, sometimes too quickly, causing it to gag and regurgitate due to clogging in the throat. Small prey are devoured whole. With larger prey, small bones are consumed, but organs and intestines are avoided along with fur, feathers, beaks, feet or hooves. The Serval utilizes an effective plucking technique in which they repeatedly toss captured birds in the air while simultaneously thrashing their head from side-to-side, removing mouthfuls of feathers, which they discard.

As part of its adaptations for hunting in the savannas, the serval boasts long legs (the longest of all cats, relative to body size) for jumping, which also help it achieve a top speed of 80 kilometres per hour (49.7 mph), and large ears with acute hearing. The long legs and neck allow the serval to see over tall grasses, while its ears are used to detect prey, even those burrowing underground. Servals have been known to dig into burrows in search of underground prey, and to leap 2 to 3 m (6.6 to 9.8 ft) into the air to grab birds in flight. While hunting, the serval may pause for up to 15 minutes at a time to listen with eyes closed. The Serval's pounce is a distinctive and precise vertical 'hop', which may be an adaptation for capturing flushed birds. They are able to leap up to 3.6 metres (11.8 ft) horizontally from a stationary position, landing precisely on target with sufficient force to stun or kill their prey upon impact. The serval is an efficient killer, catching prey on an average of 50% of attempts, compared to an average of 38% for leopards and 30% for lions.

Servals are extremely intelligent, and demonstrate remarkable problem-solving ability, making them notorious for getting into mischief, as well as easily outwitting their prey, and eluding other predators. The serval will often play with its captured prey for several minutes, before consuming it. In most situations, servals will ferociously defend their food against attempted theft by others. Males can be more aggressive than females.

Behavior

Like most cats, servals are solitary, nocturnal animals. They are known to travel as much as 3 to 4 km (1.9 to 2.5 mi) each night in search of food. Females defend home ranges of 9.5 square kilometre, depending on local prey availability, while males defend larger territories of 11.6 square kilometre. They mark their territory by spraying urine

 onto prominent objects such as bushes, or, less frequently, by scraping fresh urine into the ground with their claws. Threat displays between hostile servals are often highly exaggerated, with the animals flattening their ears and arching their backs, baring their teeth, and nodding their heads vigorously. In direct confrontation, they lash out with their long forelegs and make sharp barking sounds and loud growls.

Like many cats, servals are able to purr. The serval also has a high-pitched chirp, and can hiss, cackle, growl, grunt, and meow.

Reproduction and life history

Oestrus in servals lasts for up to four days, and is typically timed so that the kittens will be born shortly before the peak breeding period of local rodent populations. Servals are able to give birth to multiple litters throughout the year, but commonly only do so if the earlier litters die shortly after birth. Gestation

 burrows. If such an ideal location is not available, a place behind a shrub may be sufficient. The kittens weigh around 250 grams (8.8 oz) at birth, and are initially blind and helpless, with a coat of greyish woolly hair. They open their eyes at nine to thirteen days of age, and begin to take solid food after around a month. At around six months, they acquire their permanent canine teeth and begin to hunt for themselves; they leave their mother at about twelve months of age. They may reach sexual maturity at anything from twelve to twenty five months of age.

Life expectancy is about ten years in the wild, and up to twenty years in captivity.

Conservation

Servals have dwindled in numbers due to human population taking over their habitat and also hunting for their beautiful pelts. The serval is sometimes preyed upon by the leopard
