Thank you for the information!!
I do have another cage that would work well for a chinchilla.
Right now I have a four story ferret cage for my current chin.. along with a very, very large, wired dog cage that can easily get shelves added into it.
But like you said, he may be too old, and that is my concern.
IF I do decide to get another one, I would keep the other one in its own cage for a long while, and slowly let them out in my room together, supervised by myself.
Eventually I would switch their cages, to get them use to each others sent... Or I would do that step first.
I would rather get a male, as breeding could become more complicated, and my intentions aren't to become a breeder...
I work, and school, so by the time I get home it is late, I have a couple hours a night with him, so I feel bad when he is alone
Thank you for your opinion, and if you have any other thoughts you'd like to share, I would LOVE to hear them!!
