A Snowtown woman returned from a weekend trip to find that her pet freshwater crocodile, Pinocchio, was missing.

South Australian Police confirmed the crocodile had been stolen from its cage and are appealing for the public to help.

Owner Lorraine Samuels says she is worried about what may have happened to him.

"My worst fear is that someone has eaten him because crocodile meat has become a delicacy."

Mrs Samuels says she hopes that someone who really, really loves crocodiles has her 70cm long pet.

"He's gone...and now we've just got an empty enclosure sitting there. It's very sad."
