The death of a baby Red Panda is believed to have been caused by fireworks set off for a holiday. Zookeepers at the Edinburgh Zoo in Scotland say that it was pyrotechnics that caused their 3-month-old panda Roxie to choke on her own vomit after being stressed by the commotion going on November 5.

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.

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.
