What is the typical respiratory rate range for rats?

Explanation:
Rats breathe very quickly even when at rest because of their high metabolic rate and small body size. The typical resting respiratory rate for a healthy adult rat is about 70 to 120 breaths per minute. This range reflects normal gas exchange needs without extra stress or activity. When measuring, keep the animal calm and count breaths for a short period to estimate breaths per minute. The other ranges don’t fit resting rats: 10–20 breaths per minute is more like human resting rates and is too slow for a rat; 40–60 breaths per minute is slower than the usual resting rate for a rat; 200–300 breaths per minute would indicate severe distress or a serious respiratory problem.
