My cat is pregnant and at around 11:30 AM today her mucous plug came out she’s been panting all day and been really loving. Tonight about 12:30 Am she started pushing and an amniotic sac came out and she licked it and it busted. She got up right after that and started walking around meowing a little bit it’s now 1:30 AM and there still no kitten. Is this normal? Should I just put her in the room where her nest is and shut the door and leave her alone. this is her second litter her first one went perfect she had seven kittens and all seven survived but I didn’t see the first few come out during her first litter so I’m not sure what is normal. Please help!
