LIKE the 214 bus, you can wait what seems like an age to see a sugar glider possum – and then two come along at once.

Days after the Tribune revealed that one of the leaping marsupials had flown into a sixth-floor flat in Clerkenwell, a report of another glider was posted online this week. A woman who works in Farringdon said she also had helped one to a vet.

The RSPCA advises not to keep them as pets, so where are they all coming from?
