Fireworks likely caused the death of a baby red panda at Edinburgh Zoo after she became so stressed that she choked on her own vomit, experts from the Royal Zoological Society of Scotland (RZSS) said on Thursday.

A baby red panda has died due to “stress caused by fireworks” after choking on her own vomit just five days after her mother died, according to an animal rights group.

The zoological society is now calling for greater restrictions on the extensive fireworks displays that are a trademark of Bonfire Night, also known as Guy Fawkes Night, the Nov. 5 celebration named after a participant in a failed plot in 1605 to kill King James I.
