My cat went into labor around 1:00 p.m, I put her in a birthing place between checking on her she had a kitten (feet first) that was stuck halfway. We pulled it free but it had died. That was around 5:00 p.m. It is 6:30 the next day (over 24 hours) and she is not making any noise or seems in pain but there feels to be more kittens in her belly. What should I do? Is this normal?
