Yuna, I think, is the fourth hamster I've had. She loves walking upside-down on the ceiling of her cage by hanging on the bars, and I've found out that she will eat food upside-down if I feed her through the bars!
Quoll isn't even a year old, but is getting very big! She knows how to sit, shake her paw, lie down, and sort of roll over. She is also very fast!
