My cat (9mo old) had what I assumed to be a stillborn kitten. I found it around 11am. My cat was very concerned about her kitten, tapping it to try and wake it up. With the vets advice I removed the kitten from the room. After my cat was a little more labile than usual it would still enjoy attention from me. I took her to the vet at 3pm because I didn't know if she was finished delivering. The ultrasound showed at least 2 kittens with beating hearts. It is now 3am. Clearly a lot of time has passed since her first kitten. She is not showing any distress but is nesting. How long until she goes into labor to deliver the other kittens. What complications should I worry about. Do I need to be watching her 24/7 or should I let nature take its course? I plan on calling my vet in the morning. Just wanted to check to see if anyone had experience with this. Thanks, Jen
