Red pandas are native to the eastern Himalayas and south western China but have become an endangered species, mainly due to habitat loss, human interference and poaching.
Roxie was born in July, taking the number of captive red pandas at Edinburgh Zoo to four, and a fifth arrived in Scotland from Whipsnade zoo in October.
But on 31 October, RZSS, which runs Edinburgh Zoo, announced the death of nine-year-old Ginger, and her kit Roxie died five days later.
New firework control powers
New powers banning the use of fireworks came into force in four areas of Edinburgh between 1-10 November – though this did not include the area around the zoo.
Ben Supple, RZSS deputy chief executive, said baby Roxie had access to her den on Bonfire Night but the “frightening noises” appeared to have been too much for her.
He said: “Roxie had recently lost her mum Ginger but was responding well to specialist care from our expert team and was feeding independently.
“Very sadly, she choked on her vomit on Bonfire Night and our vets believe this was probably a reaction to fireworks.
“We know that fireworks can cause stress to other animals in the zoo and we cannot rule out that they may have contributed to the untimely death of Roxie’s mother Ginger, just five days’ earlier.”
Watch: Fireworks set off on Scottish streets on Bonfire Night
There was widespread disorder across Edinburgh on Bonfire Night – missiles were thrown at police in Gilmerton and Sighthill and there was two instances of attacks on firefighters in the city.
Police have made a number of arrests and on Thursday, confirmed four teenage boys – aged 15, 16 and two aged 17 – had been charged in connection with fireworks offences relating to Bonfire Night in the city.
