Kittens at three weeks old

On Saturday the kittens were three weeks old. they are now taking life at a run and love to fight with each other.  Another great game is killing mums tail and biting her ears! They love a cuddle and will sleep for ages on my daughters laps or around my neck! Turbow is more than happy with this as it gives her a break! LOL

Their weight this week Inky now weighs 500grms and Pinky is lagging behind at 470grms. It's strange as I thought Pinky looked bigger, I weighed them twice just to be sure? All I can think is Pinky runs around a lot more thank Inky?
