First 4 weeks:

As with most litters, each kitten has showed signs of a distinct personality from the beginning. Anna was the first to open her eyes and her mouth. Any time any human or animal entered the room, she had something to say about it. Elena was shy and timid, as was Igor. Yuri was brash and confident, and Andrei was sweet and compliant. Being picked up and passed around didn’t bother him, and neither did being left alone. Anna, Yuri and Andrei were the first to climb out of the nest and explore the environment.
