THANK YOU, ALL! There are so many similar genetic examples out there and it's quite confusing, as so much cross-breeding has been done. But yes- after finding some example pix, Pastel does seem to capture the description the closest and makes a lot of sense.

This sweet girl appears very healthy and friendly so I couldn't say no... and didn't think to ask too many questions at the offering. I'm going to say 8-12 months old and that's close enough. While it would be nice to know more... she is eating, alert, bright eyed and curious. That's what matters. Now I just need to get her moved into a better habitat than she came with. Free is never really free...
