I packed the Framboise Family into their carrier and they all went in to see the vet today. They wanted to recheck Cleo's eye, and make sure everything was A-OK with that. And it was. Still no cause for concern about the tongue thing and there doesn't seem to be anything physically wrong with them.
Everyone is healthy and are gaining weight and growing like they should.
I don't think I'll every grow tired of the sign of an adorable Framboise with a teeny-tiny tongue sticking out. I'm guessing you won't either, so as long as they keeping doing it, I'll keep sharing photos of it!
