How can you tell how old a gerbil is?
There's no way to tell for sure, but if they looked young in the store, they were probably 5-10 weeks old when you got them.

How Can I tell how old my iguana is?
A true hatchling will have NO spikes at all ... if they have small appearances of spikes then they are no longer true hatchling. You can usually go by the true age when the start to show there pores to identify if they are male or female. http://www.greenigsociety.org/malefemale... It is hard to truly know the age of the iguana, specially if bought from a pet store. Plus most national chained pet stores do not know the proper care of an iguana to begin w/. Young iguana if given the proper living space, humidity, heat, food, UVB should grow at least 1-3inches a month, if not more.
