I found a stray cat on a sofa outside my house I looked at it and it wasn't breathing. So I tried to revive it and it didn't work. The mother still looks pregnant and just keeps laying down. What do I do? Its been 4 hours and no more kittens have been delivered...

Cats can postpone labor for a bit when disturbed or feel uncomfortable. You may just have to keep a watchful eye. Another member posted this website today it is very informative and may be of great help to you.
