A stone's throw away from London, the Cat Survival Trust has the largest collection of snow leopards outside of Asia and with numbers seriously threatened in the wild something is being done to safeguard their future. Something remarkable, unconventional and very surreal!
Adrian Cale follows pregnant snow leopard Irbis as she prepares to give birth to her third litter, while some of the other females are moved to a newly-built breeding enclosure.
Terry Moore updates Adrian Cale on Irbis's labour, and looks to the future of the breeding project by turning his attention to the young snow leopard, Nina.
Adrian Cale goes on a road trip with Terry Moore to Exmoor Zoo to collect a new male puma called Toffee - and tries to get the big cat to mate with the Trust's two resident females, including beautiful puma Crunchee.
As winter arrives, the already high tension between sister snow leopards Omega and Nina is taken to the extremes when they are introduced to male Cato for breeding purposes.
Cato the male snow leopard starts courting Omega, for the joy of Terry Moore's breeding programme.
In the series finale, pumas, lynxes and snow leopards all find mates, and baby snow leopards are born.
