A cat in New Zealand has behaved in a very un-feline manner, bringing his owner a bag of marijuana and leaving it at the door. Police are now praising the furry friend for possibly helping them secure a drug bust as they dust the bag for prints.

Local police say they are very impressed with the deed.

''You hear of cats bringing dead birds and rats home, but certainly in my career I've never seen anything like this before," Sergeant Reece Munro told the local Otago Daily Times. “I guess you never know who’s keeping you honest these days, do you?”

At around 6pm on Sunday in Ashmore, the cat brought home 5 grams of pot in a bag, shocking its owner, who wanted nothing to do with the find and called the police immediately, saying there was a “bag of drugs” right at her door.

The police add that the bag was worth about NZ$100-$150.

Although the origins of the marijuana have not been discovered yet, the police are thankful to the animal for doing them a service, as the bag is being checked for prints.

“We will continue our investigation and look at having the plastic bag fingerprinted,” Munro confirmed.

The possibilities that exist with using sniffer dogs could now have expanded into the cat world as well.

“We certainly have police dogs trained to detect drugs – [cats] might be something police could explore in the future,” Munro added.
