9-month-old white tiger cub dies in Delhi Zoo

He added the cubs also suffered from Vitamin D and calcium deficiency as well as bone-related complications. While they had recovered from all ailments as well as the fractures, they remained under observation at the zoo hospital due to the cold.

“As it is winter now, we refrained from sending them back to their enclosure and kept the cubs in hospital under observation with heaters around them… we also provided them a standard diet,” said Bhawal.

“One of the cubs caught lung infection suddenly… cold from the heavy rainfall in December may be one factor but the lung inflammation could have occurred due to other reasons as well. Of the three, one was completely healthy and the condition of another was not very serious,” he added.

Delhi had witnessed record-breaking rainfall on December 27, when it received 41.2 mm of rain – was the highest recorded rainfall in 24 hours for the month of December since 1923, as per India Meteorological Department.
