Well, T-Bird (alias Lady Tiara) is three now, and I keep waiting for any kind of hormonal behavior or an egg. She has torn up paper at the bottom of the cage and crouches there for a time each day, but her personality has not changed one iota. If anything, she is even more affectionate. This little girl has not bitten hard ever. She went through the lunging nippy state at 7-9 months, then became a cuddling, kissing bug...and has remained so.
I keep wondering if I've done something right, or she is just an exception ekkie!
