Edit: Ebony continued not to grow and had to be put to sleep because she just shut down 10 days after we got her and Nala had a bad upper respiratory infection. The shelter adopted out sick cats.
Ebony (left) is the dominant runt who likes to explore, Nala (right) is the affectionate insecure one who always needs touch to feel safe. Her sister tolerates all sorts of touch from Nala when they sleep, even feet to the face. I'll upload that one next. They are about 10 weeks old right now.
