A possum's sweet tooth has come back to bite it after getting its head stuck in an empty jar of Nutella.

The marsupial was found out the back of a home in Loganholme, south of Brisbane, on Monday, with its head firmly stuck in the plastic jar.

RSPCA Queensland spokesman Michael Beatty said the possum was found by a man after his dog showed "great interest" in the bins outside.

"The man looked around the back of the shed near the garbage bin and there was the possum with his head caught," Mr Beatty said.

"It managed to get his head in the jar, but obviously couldn't get it out."

The home owner called the RSPCA's animal emergency hotline, and a volunteer attended and was able to free the possum with the help of a water-based lubricant.

They took the possum to the RSPCA's native wildlife hospital at Wacol for observation.

"They were worried he may be badly dehydrated, they didn't know how long he had his caught in the jar," Mr Beatty said.

He said it wasn't the first time they've been called out to help possums caught in peculiar positions.

"I've seen some stuck under stairs, and occasionally they might be trapped in a drain or something like that," Mr Beatty said.

"There was one possum that got into a box that had all these cakes in it and then it couldn't get out."

The possum was released on Thursday back into the wild close to where it was found.
