Speakers, at an event in the city, have demanded a stop to the practice of feeding live animals to other animals in cages at zoos.
They put forward this demand at a press conference arranged by Bangladesh Rabbit Group at the National Press Club on Tuesday.
Addressing the event, wildlife and environment expert Md Abu Sayeed said that in foreign zoos, rats are refrigerated and fed to snakes after keeping them for a while at room temperature. But animal rights are being violated here at home.
Dr Firoz Zaman, professor of Department of Zoology at Dhaka University, said every animal species needs a balanced environment in the planet to thrive. If all the birds are kept away from the earth for 4 minutes, the planet will be destroyed, he added.
Afzal Khan, founder, and chairman of Robinhood the Animal Rescuer, said, ''If animals are trapped anywhere in Dhaka city, we have rescued them, putting our own lives at risk, and bearing insults and humiliation along the way. Your own sense of awareness will certainly make our lives easier."
Nadia Binte Alam of Bangladesh Rabbit Group said, ''After speaking to Animal Researcher team members in different countries, we learnt that certain basic protocols are followed even if animals are used to advance scientific research.''
''Live animals are never fed to pythons in other countries. But you all know what happens in zoos here in Bangladesh,'' she added.
The practice of feeding live animals to captive animals in cages has recently drawn much criticism on social media, particularly Facebook.
There has been quite a lot of backlash on social media since January 29 when Tanjil Ahmed, from Laxmipur, posted a picture on Facebook of the Bangladesh Rabbit Group.
