Kangroo + pig = ?

What do you get if you cross a kangaroo with a pig ? A non-viable embryo, hopefully.

A pig and kangaroo kept in a captivity in northern Australia appear to have formed a rather close physical bond. Animal behaviour scientists say the conduct of the pair, kept at the Aileron Roadhouse in the Northern Territory, is rare and surprising.

The owner of the roadhouse, Greg Dick, told the BBC that the animals spent a lot of time together and had "been in love for a while". Experts say the "aberrant" behaviour developed due to years in captivity. Mr Dick said he had seen the kangaroo sleeping with, cuddling and "carrying on too busy" with the female pig, named Apples.
