So, soon I am getting another chinchilla and I decided to ask this question in advance. How should I introduce them and should I ever let them run around or do thing out of their cages in the same room together? They will be in separate cages but sometimes I let my only current chin run in my room but should I let the two of them run around at the same time? my largest number of chins at a time is 1. I am new at this so could I get some information on this? thanks
