snow leopard museo de historia natural - chapultepec zoo has not had a snow leopard until recently,so this one was most like taken from the wild. this is .a popular diorama
Deteriorated museum specimens that we observe nowadays were made decades (and some - ages) ago, when taxidermy technologies were not advanced.
Modern mounts do not deteriorate if kept in special environment (dust-free glass exhibits with correct humidity, temperature, and no UV light - it causes color fading)
