Which species? I’d like to know more
Marbled cats were at a private facility in England until just a year or two ago. There are a fair handful scattered about Asian facilities and this is one that might turn up again.
Saiga have been tried and failed in zoos because they're skittish, I don't know more detail or about the others
This is incorrect. One of the biggest issues with the Saigas kept in North America and Europe was their sensitivity to climatic factors. They dislike cold and humid, and it causes health issues which they are very prone to. Saiga are also extremely prone to parasite infection. Several places that formerly kept saigas had breeding success but very low infant survival rates. Added on with shortened lifespans of the adults due to other issues mentioned and most groups didn't last all that long.
Sumatran Rhino only has 80 something individuals left in the world. The last one to be kept at a public zoo was transferred to Asia to help the population.
Harapan at Cincinnati, the last of several rhinos in both NA and Europe. Seems crazy to think this was still less than a decade ago...
Sumatran Rhino is unlikely to ever return unless something extremely major turns around for the species.
Pampas cat has been kept on both continents in the not too distant past, I think it was mostly lack of interest that saw them disappear.
Streaked Tenrecs have also been kept on both continents, I think Europe has only just recently lost them. My understanding is the conditions for successful breeding were not often met, and as such breeding was limited.
I do know Flat-headed Cat, Andean Cat, Chinese Mountain Cat, Short-eared Dog, and Crab-eating Fox have all been kept in Europe at least occasionally within the last century. Chiru is the only species I'm not aware of having been kept.
