hello, my cat has just had her first litter (they 2 weeks old now), towards the end she was looking for a nest all the time she was checking out wardrobes and chests of drawers, i also noticed that i could see the kittens moving inside 2 weeks before she had them, she was also very restless the day she had them and followed me everywhere meeowing at me, she then vanished from sight and had them behind my curtains in the front room. Hope this helps x
