Rats commonly travel how far from their nest while foraging for food and water?

• A. 50-100 feet
• B. 100-150 feet
• C. 200-300 feet
• D. 400-600 feet

Answer: (B)

Rats typically stay fairly close to their nest when foraging. The common foraging radius is about 100 to 150 feet, which is roughly 30 to 45 meters. This distance balances the need to access reliable food and water with the energy cost and risk of travel. In urban areas with concentrated resources, most foraging happens within this nearby zone, so 100–150 feet is the best-fit range. Distances shorter than that (50–100 feet) may occur in very rich, nearby sources, but if resources are not immediately adjacent, rats will still generally limit their trips to around the 100–150 feet zone rather than going much farther. Distances like 200–300 feet or 400–600 feet are less typical because traveling that far increases energy expenditure and exposure to predators or traps, making it a less efficient foraging strategy.
