Hello, I have 2 Chinchillas. 1 female that i know is 4 that has never been bred, i have had her for a month and i dont know if she has been in heat since i have had her. And i have a male that the prev. owner said was 1 but i think he is way older. I wanted to know since my female is 4 and has not had a littler before, if it is too late to start her. She is a Standard and the Male is a Hetero Beige( they did not tell me he is, i am gathering that he is from researching)(pics of them are in my albums) I out him in her cage right when i got him and they hit it off pretty well, She did nibble at him at first but they are buddies now. Even though they are friends and have been together only 2 weeks, does she still have to feel comfortable around him to want to mate with him?
