Yes. They must have been at Flamingo Land for quite a time now. I believe they are the daughters of the infamous Balkash (I think that was his name wasn't it?) at Howletts - at least I read that somewhere.
I've found some of my 2010 photo CDs and there's one of their exhibit I'll post in a minute. The only one I've found of the Sumatrans' exhibit, by the way, is pretty much the same as camel leopard's on page two. I think I've got more pictures of the animals from last year, so I'll look over the weekend.
