"Vijay's cage is being beautified. Painting and grassing of the enclosure is on. The nets are being replaced. A new ramp will be made," Riyaz Khan, zoo curator said.
The white tiger, his mate Kalpana and their four cubs live in the enclosure together.
The zoo official said the feline family is now being shifted to another enclosure and will be brought back to the renovated one after a few weeks.
Vijay had mauled a 20-year-old man to death in 2014 as stunned visitors looked on. The incident was widely shared on the internet. Since then the 9-year-old male white tiger has become a star attraction at the National Zoological Park, which has seven white tigers.
