Orphaned joey climbs into adoptive dad's pouch as new name revealed

The orphaned joey adopted by a Western Australian policeman is already treating the officer like his mum.

In an adorable video, uploaded overnight to Facebook to reveal the name chosen for the baby roo, Constable Scott Mason grins and patiently tries to keep speaking to the camera as his new companion clumsily crawls into his shirt like it’s a pouch.

"So, ladies and gentlemen, that's Cuejo," Constable Mason says with a smile as the orphan snuggles against his stomach inside his shirt.

The name refers to a tail's wag, according to online dictionaries, but it is also the name of Brett Craig's rottweiler on the hit TV comedy Kath and Kim (though the program spells the dog's name Cujo).

Constable Mason, a former paramedic with a passion for animals, adopted the joey after its mother was hit by a truck in Western Australia's remote mid west.

Cuejo was brought into the Cue Police Station earlier this week after being found in its dead mother's pouch.

"It's very dehydrated and skinny, but we're doing what we can," Constable Mason said.

The young officer — who moved to Cue six weeks ago — said he would have his hands full over the next few months as his wife just gave birth to their first child.

"Because it needs to be fed every three hours, it's going to be my little child basically as my wife's in Perth with our newborn," he said.

"So she's got her newborn and I've got a little one as well."
