Is it safe for my cat to give birth at home?

Yes, but watch. She should have a kitten within 30 minutes of actively pushing and about two hours between kittens. So if she's not pushing, she can take a little bit of a break, but about two hours between each kitten coming out is what you should look for. Anything beyond that would be a red flag. Other things to watch for would be black discharge coming out. Black discharge is not good, and the same goes for bleeding. Delivery in cats is not usually a bloody process, so if you're seeing blood, that may be a sign that we need to do something about it.
