I recommend passing on this one. The female may already be pregnant. You might not know for a while since gestation is 100 days. Neutering is very risky as well. Separating a bonded pair can also be a nightmare especially if the surgery kills one because it can cause severe behavioral problems. You can probably get a chinchilla for about 150 dollars at a pet store but I would recommend a local breeder who carefully monitors their genetic lines for congenital disorders.
