Cats can deliver kittens with longer breaks between than dogs. I recommend keeping her separated in a quiet area and letting nature take its course. It is very unusual for cats to have trouble with labor. If she has not passed another kitten in 4-5 hours I would call your local vet for direction. At anytime if she is not eating.,drinking, or acting properly I would take her to the vet

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Cats can delay labor for a maximum of 24 hours. If it has been longer than 24 hours then that constitutes an emergency. If you are concerned about a retained kitten that hasn't been born great than 24 hours after the birth of the last kitten I highly recommend a Vet appointment. They can take an X-ray to confirm she is finished. I wish Chloe the best!

    While cats can take a break between kittens, 20 hours is long time between kittens and I would take Kitty into the vet now to be safe. Be sure to bring all her kittens with her as well. Best of luck!

    Hi there. No, it's normal for labor or birthing breaks to last that long. I wish there was something at home you could do, but the best thing would be to get her in right away. I hope she feels better soon
