I know there are a lot of topics about chinchillas in heat, but I'm a little suspicious of my "girls". If you've read any of my other posts, you know that I have little reason to trust the pet store I got my girls from. So how do I trust that they're both girls? I have no way of checking them, Kira will probably never let me hold her.
Anyway, I ask because I think Kira's in heat. There's little doubt really. She's been doing the "swish swish tail dance" a lot, grooming M'noke, licking her head, and trying to mount her. She doesn't ever seem successful, but do girls mount? And should I be preparing for a litter? I've had them since November, so we figured we were safe. We don't really want to be breeding them, so I'm not sure what to do if we have a boy and a girl!
Could anyone more experienced with chinchilla breeding help me identify this behaviour? Thank you so much in advance. I don't want any surprises in 111 days!
