The Andhra Pradesh forest department is yet to reunite the four abandoned tiger cubs found in a village in Nandyala district with the mother, an official said on Wednesday. The 48-hour timeline crucial for the tigress to accept or reject the litter has lapsed. However, the all-female litter is doing fine and active, while the search for the mother continues.“We have a brief idea as to where the mother is with the recent pug marks but we don’t know the exact pinpoint location,” said Allen Teron, deputy director, Atmakur, Wildlife Division, Nagarjunsagar Srisailam Tiger Reserve (NSTR).
