wow, s/he doesn't even look old. I remember the ones at the Mini Zoo in Chch back in the 80s (the ones the Franklin Zoo ones descended from), and they never moved much. Of course, they didn't have much in the way of space to move in, but they did sleep most of the time.
When the zoo closed down in the 90s, the pair went to Pouakai Zoo. The two at Franklin were bred at Pouakai, went to Hamilton, and then from there to Franklin. Pouakai still has either one or two (the original female and a daughter; I think the older female may have died in the last year or two but I can't recall). I'm guessing the Franklin siblings must be around 10 or 15 years old now? [Just re-read your review, and it says they're nine years old, so I was almost right]
Do you no if there were any other decendents from the original par besides from the daughter who was Living with her mum at Pouakai zoo and how old the animals were when they died thnaks
