KEEPING and feeding a marijuana-munching feral pig on his Meringandan West farm was never going to end well for Jason Clifford Grice.

Toowoomba Magistrates Court heard police who visited the property on October 7 on another matter spotted a fully grown feral pig chewing on a marijuana plant in a pen.

"Do they (feral pigs) like marijuana?" an inquisitive Magistrate Damian Carroll asked, prompting police prosecutor Sergeant Mike Robinson to reply, "Apparently, this one did".

Grice, 45, was initially charged with producing and possessing a dangerous drug arising from the pig's marijuana plant for which he - Grice, not the pig - was fined $900 after pleading guilty before the court last month.

However, Toowoomba Stock Squad detectives later attended the property in relation to the feral pig and Grice was charged with keeping a declared pest and feeding a declared pest animal, Sgt Robinson said.

He pleaded guilty to both charges.

His solicitor Chris Lumme told the court his client instructed he had been given the pig about 12 months earlier by a friend of his girlfriend's.

Grice told the court the pig remained on his property and he was in the process of applying for a declared pest permit so he could keep the porker which had been treated and wormed.

Mr Carroll warned him that the maximum penalty for keeping a feral pig without the relevant permit was almost $48,000.

However, taking all matters into account, Mr Carroll fined Grice $800 and ordered the convictions not be recorded.

Mr Carroll gave Grice until January 22 to obtain the relevant permits or the pig would be forfeited to the Crown.
