I have read quite a bit about introducing chinchillas, but I would like some personal advice.
I have a 2 1/2 year old female chin. I recently got an 11 month old male chin.
They are both healthy well bred animals and I do intend on having pups. I have done my research and pup proofed the main cage. Please do not turn this into anything other then introduction advice.
They were initially placed side by side with a small gap in separate cages. There was minimal reaction or interest by either one. They were quickly virtually ignoring each other and happily sitting on the adjacent sides comfortably. After a week I switched them into eachothers cages. I have switched the dust bath around with used dust. It has been 3 days since the cage switch and they are both still relaxed. In experienced opinion, how much longer should I wait before a neutral open introduction?

I would also like to add that my female is an ebony sapphire carrier and my male is a sapphire. I am fond of chinchillas and interested in genetics and bloodlines.
