<human>: Give me the gist of the text in a nutshell

I figured all you cat lovers would be able to shed some light on what we need to do for this pregnant girl.
First of all, I want to be clear that this is not our cat.  We had some new neighbors move in and they have 2 or 3 dogs and about 4 or 5 outdoor cats.  Well this little girl, very young, (she is the cutest thing under the sun fyi) started spending a lot of time at our house on our back deck.  We were told the if cats are in a hectic environment that they will seek out a calmer one, and it is pretty hectic over there.  Well, naturally, we started putting food out for her and all was good.  We hoped she was spade, but it turns out she is now very pregnant.  
We want to make sure she is as comfortable as possible since we assume she will give birth at our house and also want advice on what to do when the kittens are born.  We want to give them back to my neighbors since they are the irresponsible party here but at the same time we don't want them to be given away to early and not have had time to learn from their mother.  I know we need to make sure our miss. Kitty gets spade (that's what we call her) but also that all their cats get fixed.  Is there a legal way to force it?  Could they get in trouble?  What should we do for miss kitty to make her birthing process as smooth as possible?  We literally know zero about caring for cats so any and all advice is more than welcome.  Thank you guys!
<bot>: Neighbor's cat is pregers and spends most of her time at my house.  No idea how to care for or help a pregnant cat or how to deal with our irresponsible neighbors, please give tips and tricks.
