Temperature range for gerbils

Question
I know that ideally, gerbils like 59 to 68 degrees, but how low a temperature can they tolerate before it becomes a problem?  Do you know??
Thanks,
Mark

Answer
Gerbils orginate from Mongolia where their habitat is mostly desert and grassy steppes.  There the temperature fluctuates between 40-122 degress Fahrenheit at different times of the year.  I'd say optimum temperature is 68.  I wouldn't recommend keeping them at anything below 50-55 for long periods of time as it could make them more susceptible to respiratory problems.  However, like any mammal, they can survive and adapt to a wide variety of climates.
