During evening rounds, how many times do mice typically feed?

• A. 5
• B. 10
• C. 20 or more
• D. 50

Answer: (C)

Mice feed in many short bouts rather than one or two large meals. Their small stomachs and high metabolism mean they nibble frequently throughout the night, visiting multiple food sources and taking repeated, tiny bites. Because of this constant foraging behavior, the total number of feeding events during an evening or night can easily reach twenty or more. A smaller number, like five or ten, underestimates how often they take in nourishment, and fifty is unusually high for a typical night. So twenty or more feedings best reflects how mice actually eat during the evening rounds.
