What is the typical heart rate range for hamsters?

• A. 300-500 bpm
• B. 50-100 bpm
• C. 900-1100 bpm
• D. 150-250 bpm

Answer: (A)

Hamsters have a high resting heart rate because of their small size and fast metabolism. When they’re calm and at rest, their heart usually beats in the high hundreds per minute, roughly three to five hundred. That makes a range like this the best fit for a typical resting heart rate. The other options are not representative: 50–100 bpm is far too low for a hamster, 900–1100 bpm is unusually high and would indicate extreme stress or unusual conditions, and 150–250 bpm is also lower than what is typically seen at rest. Remember that heart rate climbs with activity or stress, so resting measurements sit firmly in the hundreds per minute.
