Oh Gretta-Monster and Dali Hissy-Pants were little terrors right out of the shipping box. My avatar is actually the first picture I took of Dali in her little deli tub.
Dali's gotten better, she doesn't throw a fit anymore but she doesn't like to be handled, but Gretta's just always been a pain. She was stand-offish and defensive at first, and about two months after we got her, my boyfriend was holding her on his lap while I cleaned her tub, and she nailed him right in the face.
It's definitely not a typical amarali attitude, and I've noticed that most of mine have gotten sweeter as they've matured.
