Pandas 'costing zoos too much'

American zoos say they are struggling to afford the rent on pandas from China - and may have to send the cuddly creatures back home if prices cannot be cut.

Keeping a pair of giant pandas, with their huge appetite for freshly harvested bamboo and demands for special attention, costs around $2m (€1.66m) a year – at least $1m (€830,000) of which is paid in fees to the Chinese.
