Officials at the Edinburgh Zoo want lawmakers to ban pyrotechnics after concluding that they caused 3-month-old Roxie’s stress-induced vomiting.

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.

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.
