Forest officials said their deaths were "not natural".
A five-year-old leopardess was found dead on the outskirts of Sarasiya village near Dhari town today, officials said, adding that she was injured and died due to injuries.
An inquiry has begun on how the leopardess got injured, they said.
In another incident, one leopard was killed after a fight with a lion in the Dhalkhania range of the Gir forest today, forest officials said.
Fighting between lions and leopards over territory is common and lions end up winning such fights most of the time, since they are stronger animals, they said.
