African Lynx
What's the African lynx? It is an early name for the well-known, small-to-medium sized wild cat species the caracal (Caracal caracal and formerly Felis caracal). It was the given name in the early days of the taxonomy of the wild cat species as it was and is the only lynx-like animal in Africa. I think this is a reference to the ear tufts. It has also been called the desert lynx and Persian lynx.
As the caracal's distribution includes the Middle East and western Asia (or did) the term African lynx was abandoned in favour of 'caracal'.

How can cats jump so high?
The answer to the question is all about mechanics and muscles. The domestic cat and indeed the wild cats have lots of fast-twitch fatiguing muscle cells. These cells are designed to propel the animal quickly; to allow the animal to accelerate quickly, but they're not very good at prolonged effort because they tire. The cat is a sprinter rather than a long-distance runner such as the African wild dog, mule or horse.

The second reason is all about the mechanics, the leg bones, particularly the hind leg bones of the domestic cat which are long. The muscles working to move these long levers allow the cat to jump so high. The concept of long levers applying a stronger force than short levers can be seen in bolt cutters. They have long handles. And if you want to unscrew a nut which is rusted in or very stiff, if you use a long spanner you will be more successful than if you use a short one.
And of course the hindquarters of a domestic cat and the other cats such as the mountain lion are very powerful. When these muscles contract quickly combined with long levers the cat is propelled forward either to attack an animal or leap upwards.
There is also the matter of power-to-weight ratio. The heavier cats will be less good at jumping than the lighter species. The lion, for instance, is not a great jumper relative to the leopard which is considerably lighter.
The lion is built to grab hold of large prey and subdue them. This is why their arms (forelegs) are immensely strong much like the tiger's. This power-to-weight ratio is best seen in the caracal which is a medium-sized wild cat species. This is the cat that jumps the highest. They have an ideal power-to-weight ratio. The picture below is of a caracal catching or trying to catch a bird (or an object thrown by someone to simulate a bird) in flight:

All the medium-sized cats are probably more adept at jumping vertically than the big cats. There is too much inertia to overcome in a big cat and the power-to-weight ratio is not as good as for the smaller species.
And one of the factor which may play a role as to why cats can jump so high is the floating shoulder. The forelimbs are connected to the rest of the body by muscle. The cats clavicle floats and is anchored by muscle. This allows cats to lengthen their stride and it enhances the range of motions that cats have. This indirectly helps a cat to jump well.
The cat's foot is elongated and it looks like a leg bone but it isn't. At the end are the toes and cats walk on their toes because they are digitigrades. I would argue that this also adds to the leverage that a domestic cat has which once again supports the ability to jump high and horizontally over long distances.
The video on this page is of a female F1 Savannah cat whose name is Magic. I don't know whether she is alive still but at the time she was the tallest domestic cat to the shoulder in the world. Savannah cats of this type i.e. first filials have a serval father and the serval has the longest legs to body size of all the wild cats. That's why the F1 Savannah cat is such a fantastic upwards jumper. Once again it's about leverage using long levers.

African Lynx
"African lynx" is an earlier name for the caracal (Caracal caracal). It was given to this medium-sized cat because it is the only lynx-like animal in Africa. The name was misleading because the caracal is also found in the Middle East and western Asia. The term African lynx was abandoned in favour of caracal.

I have written a lot about the caracal and therefore won't go over those topics again here. If you want to read more about this highly athletic medium-sized wild cat which has the highest jump of any cat on the planet from a standing start then please click on this link. You'll be taken to a whole range of articles on the subject.

Caracal Kitten Makes Strange Sound
The experts say that this medium-sized wild cat species has the 'basic felid vocal repertoire' by which it is meant that the sounds made are typical of cats and include meowing, gurgling, hissing, growling, spitting and purring. These are all sounds barring gurgling that the domestic cat makes. They also make a sound called the wah-wah call. Other wild cats have this call namely, lynxes, pumas, jaguarundi, servals and the Asiatic and African golden cats (you can read about all these cats on PoC).
One expert, has reported hearing caracals making a harsh, hissing bark when a strange animal was introduced into an enclosure.
You'll also notice the beautiful ear tufts. The caracal has the longest ear tufts on any cat, domestic or wild, on the planet and it is thought that they assist in communication but the function remains unknown. They may accentuate facial expressions. They may facilitate the location of sounds. One expert, Kingdon, believes that they are a 'decorative signalling structure'. I have a post on this: click here to read it.

Caracal Pictures
This species is famous for its fabulous leap from the ground, its very long ear tufts - the longest and most pronounced of all cats, wild and domestic - and its ferocity!
It has been tamed in the past as has the cheetah; tamed for use in sport hunting. Hunting with cheetahs.
