**Indonesian conservation officials have discovered four fully-grown tigers at a house in Jakarta, along with several rare cockatoos and birds of paradise.**They are now trying to establish whether the tigers belong to the endangered Sumatran species, of which there are only about 400 in the wild.
A conservation officer told the BBC they were looking for the homeowner.
He or she could face a heavy fine and a prison sentence of up to five years for illegally keeping the animals as pets.
Earlier this month, officials discovered a pair of adult tigers and three cubs that had been raised by a man in Jakarta over the last 25 years.
The Indonesian government has said it is considering entrusting Sumatran tigers to private individuals for safe-keeping in an attempt to save the species.
Much of the forest they live in has been has been lost to illegal logging and deforestation.
