To add to the confusion, although the Thrigby animals *were* the Chinese Ferret-Badger as far as I know, I'm pretty sure they were not the same animals as had previously been held at Regents Park; the latter animals left the collection in 1967, having been at the collection for some years and never bred, whilst Thrigby went out of the species in late 1989, or possibly early 1990.
As ferret-badgers, although a little-studied group, tend to have a lifespan of roughly a decade, it is therefore very unlikely the animals were the same individuals.
