Does anyone know how Thrigby came to breed hybrids? ISIS has listed a female Sumatran and a hybrid male, another thread suggests the Sumatran female came to Thrigby in 2005. I am pretty sure Thrigby has only ever held what they thought were Sumatrans, I would suggest the animals at Welsh mountain zoo and elsewhere are 75% Sumatran. I assume the male at Thrigby is an elderly animal who is their father. Can anyone shed any light on this?
Did the original Paignton 'Sumatrans' come from Thrigby? I know they were sent to another collection as soon as it was realised they were hybrids, would this be Shepreth, or are the Welsh Mountain Zoo tigers those that Paignton discarded?
