After the death of a hippopotamus at the Byculla Zoo in South Mumbai, the People for the Ethical Treatment of Animals (PETA) has decided to work hand-in-hand with the authorities to improve the condition of the caged animals in the Zoo.

"PETA along with the Zoo authorities will involve in enrichment activities for animals before the BMC-sanctioned Rs 430-crore plan is put to action," PETA's chief functionary Anuradha Sawhney told PTI here.
