A biologist in South Africa has a unique job: he introduces big cats to each other so that they can pair up and mate



When you live in the country, the dating scene can be thin on the ground. And for cheetahs, this is a dilemma that could jeopardize the species’ survival.

Take a step forward. Vincent van der Merwe, a South African biologist, has a one-of-a-kind job. The 39-year-old exposes the large cats to one another in order for them to mate.

Vincent, who resides in Cape Town, transports cheetahs between reserves in South Africa, Malawi, Mozambique, and Zambia to help them find mates and diversify their gene pool – an important task given the animals’ falling numbers due to inbreeding.

Inbreeding can make any animal more susceptible to sickness. Inbred cheetahs often suffer mange and other diseases, which in normal circumstances the cats would shrug off easily.

Other health problems can include smaller body size, heart defects, slower growth rate and reduced fertility.

Vincent, who works for conservation group the Endangered Wildlife Trust, tells The Independent: “I move cheetah populations between reserves to ensure genetic health and ecological balance.

“Wild cheetahs are quite promiscuous – so much so that genetic testing has found that there can be multiple fathers in the same litter. Once you introduce a cheetah into a new reserve, no initiations are necessary; they will find each other without interference and breed.”

A typical reserve that Vincent and his team visit is the size of the greater London area, and contains just 10 cheetahs. Fortunately, cheetahs have something called communication hubs, normally prominent trees or rocks, where they meet.

Males will mark these sites weekly by urinating or defecating. In doing so, they announce their presence in an area, who will visit the hubs when they are scouting for potential mates.

“No encouragement is required,” Vincent says. “Like humans, cheetahs are evolutionarily programmed to procreate. My job is simply to ensure that, within all 67 reserves/protected areas that I work with, there is at least one adult male and one adult female.”

He adds: “My work gives me a purpose in life. It’s a tonne of work, and I’m hardly ever home, but I feel as if I’m making a positive contribution to biodiversity and society.

“It helps me sleep well at night. I grew up with a deep love for Africa. A major bonus of my work is that I get to see some incredible places, the last few remaining wild places in Africa.”

Despite their famous speed, cheetahs are something of an underdog in the wild and are actively hunted by lions, leopards, and hyenas. Half of cheetah deaths are caused by these three predators.

“Sometimes we have cases where all three adult females in a protected area are randomly killed in a series of unfortunate events,” Vincent says.

“In a scenario like this, I will identify a protected area where cheetahs are doing well, and I will capture new adult females from that area and relocate them to reserves where we have lost key breeding individuals.”

Vincent manages what the Endangered Wildlife Trust says is the only growing wild cheetah population in the world. The organisation started its project 10 years ago with a declining population of 217 wild cheetahs in 41 protected areas. They now have 486 cheetahs in 67 protected areas.

Vincent’s favourite cheetah matchmaking involved a small cheetah named Bob.

He says: “When we got approval for wild cheetah reintroduction into a beautiful reserve called Majete in Malawi, I sourced two beautiful females and two large, dominant males.

“Just before we were about to fly the cheetahs to Majete, I got offered a third male cheetah that had mistakenly been identified as a female, because he was so small. We called him Bob.

“Shortly after arrival in Malawi, the two dominant males got killed, one by a warthog, and the other by a leopard. Puny Bob turned out to be a true survivor and impregnated both of the females.

“He is still alive today, roaming the wilds of Majete, being a good boyfriend to all the cheetah mums.”
