Thank you! That was very helpful! I'm not sure of their gender, they are pretty small, which makes it difficult to tell. In your experience, have you ever had a 13 mo that is an inch long? The person that bred them was housing them in a pretty small container, so I'm wondering if their small size could be due to this.

If so, this would explain why you haven't heard anything, as they tend only to vocalise when giving a 'release call' and if there are no males in with them, they are unlikely to need to. They can be hard to sex at around a year, but if you look at the hind feet, the males tend to have webbing which reaches right up to the toes, whilst the girls have webbing which doesn't extend that far up. I say tend to, because there's always the odd exception.
