Petty theft is a criminal offense involving the unlawful taking of someone else's property, typically valued at a lower amount, without the intent to permanently deprive the owner of it. This type of theft is often classified as a misdemeanor rather than a felony, reflecting its relatively minor nature compared to grand theft. Petty theft can occur in various forms, including shoplifting and stealing personal items, and is often addressed through fines or community service rather than imprisonment.
