I was going to write this off as  a fluke, since it's roughly twelve hours until adulthood, until I realized again that the gryphon showing was actually this adorable rascal, born an hour and a half ago. I now know that his appearance is going to be identical to that of another of mine.

Don't know if this is an intentional aspect of the site or not, but I can imagine someone using that tool to tell at a glance whether an animal inherited a visual gene and immediately discarding them based on that, so figured I'd report it anyway.  

Thank you for reporting! Some of the places on site display babies as adults due to an oversight, so this is a bug, but luckily not a critical one. It's not possible to discard a baby pet, and usually the color is known right after birth and written in pet's profile. So the information about full-grown appearance won't give a breeder any additional info, maybe just satisfy the curiosity in the very specific cases like baby Etelias that don't have colors but have a few morphs.

Babies should appear properly in the list of bred pets now.
