Adult female Cinnamons that you're not sure what to do with...
That's not really that bad of a problem to have.

I would pick up a male Pastave to pair with them.
That way you could make some Savanna and Pastel Savannas.

If you need to move them out to stay under your 20 animal limit, PM me for my shipping info.

Can you please post a pic of the Full BlackBack male Cinny that you used to have.
I was looking for him, but I guess all of the pics have "timed out" on the forums, and have been removed.
