Which of the following is NOT an example of livestock?

The correct answer is the cat, as it is not considered livestock. Livestock refers to domesticated animals that are raised for agricultural purposes, typically for food, fiber, or labor. Goats, pigs, and cattle are all examples of livestock, as they are commonly reared to provide meat, milk, and other agricultural products. Cats, while they can be domesticated and are often kept as pets, do not fit this definition as they are not typically raised for agricultural use. This distinction highlights the specific purpose of livestock in farming and agricultural systems compared to animals kept primarily for companionship or as pets, like cats.
