An alpaca stolen from Bringelly was recovered during a raid of a bikie clubhouse in Horsley Park.
Police on Wednesday raided headquarters of the Gypsy Jokers outlaw motorcycle gang, uncovering drugs, guns and cash.
But they also found Cleo - a brown female alpaca that was being kept in a paddock at the rear of the clubhouse.
Cleo was reported stolen from a property at nearby Bringelly in February.
Gangs squad detectives also found a loaded .32 calibre revolver, a loaded pistol, approximately 700 rounds of ammunition, and more than 200 ecstasy tablets.
Police said their investigation into the matter was continuing and they expect to make arrests.
Cleo was taken by RSPCA officers for an examination and is expected to be returned to her owners shortly.
