Cat in labor stealing other kittens

There are other solutions if not, just keep asking questions and we could help you work it out with Pet Talk peeps me thinks eh

If your cat is in labour it can't be long before she gives birth... seems she can wait to get her kittens.
How does the mom of the kittens react? She must be nearby.

The best is probably to separate the cat in labour from the kittens. Could it be that she has some problems? Perhaps have a vet check her.

Good luck!
