Help T____T my cat hasn´t delivered yet

Uhm, I´m sorry if I bother >____< but i´m really worried about my cat, Pelusa chan, she´s pregnant and she´s supossed to be delivering the kittens by these days ._.uu ... she has the symptoms (Breathing with her tongue out, she stays just in one point, liking her tummy and vagina a lot)... but since nothing happens by now... I´m worring each day more >__< ... Can she be delaying the delivery?
Pelusa likes sleeping with my mother in law, but since she and her husband adopted a puppy, she hasn't been able to slep with her anymore... she's been in a bad mood since the dog arrived and she's been attacking him too. Could it be posible that she's delaying the delivery'cause of that?
Can anybody help me T____T?

When did the vet say she was due, and when did the puppy arrive?

Stress can definitely cause a cat to delay delivery. They should put the cat in one room with a nest made up for her to deliver her kittens. (I like to use the bottom drawer in a chest of drawers - just take out the next-to-last drawer and it makes a great nest.) I suspect she fears that the dog will harm her kittens, and her fears may be well-founded. But delaying the delivery too much can be very harmful for the cat and her kittens.
