India’s ambitious plan to reintroduce cheetahs, which went extinct in the country in 1952 due to hunting and habitat loss, has suffered a setback. Three out of four cheetah cubs born to a big cat brought from Africa last year have died in Kuno National Park in Madhya Pradesh state due to a heatwave that sent temperatures soaring. The cubs were the first to be born in India in over 70 years. The mother was one of 20 cheetahs flown from Namibia and South Africa as part of the plan. The survival rate of cheetah cubs is low, and experts believe the heatwave weakened the cubs.
