When my hubby felt kitty's move she had them 2 days later. I would say if she's in and out of box and it's tucked away from other cats your good. Remember they need a lot of good food and protein when nursing ours lost a lot of weight then we broke down and bought those canned cat food! But she put weight back on and all kittens survived. She was hunting and bringing food to them at 6 weeks. We gave her along with kittens to local farm so she could keep them corralled.
