ok my kitten's are 6 week's old they have alway's been in my bedroom as it is the safest room in the house and the most quiet anyway today i let them have the run of the living room for the very first time , they loved it but there mum didn't , Lilly dosn't stay with the kitten's as much as she used to now but when i let the kitten's out she got very stressed and tried to pick them up ( witch she has never been able to do lol) they wouldn't allow her to they just ran when she tried ,the hole time they was out ( with me watching every move) she did nothing but cry going back and forth to the bedroom i felt so quilty i left them out for 1/2 an hour then put them back and she hasn't left them since is this normal for a mother cat to behave who was never really protive of her kitten's?
