My cat had a baby over 24h ago and the baby didne't make it she has been fine all today and just very affectionate around 5:00 she started acting strange like she was unconfortable and something was comeing out from behind also had some bleeding almost the same as when she was having her first baby its been 4 hours since this started and she continues to do this but nothing has come out.. is she having more baby's or is there something else going on?

It sounds like she's in labor and the baby is stuck.

You need to get her to a vet now!
