To orphaned kitten person--just a PS
I hit the button just as I thought of this suggestion--you don't say where you found the kittens, but keep an eye out for the mom. If the kittens were hidden, even in your yard, mom may just have "stepped out" for a moment. If you do contact a rescue, ask them if they have a nursing queen in their shelter or foster homes. They may be able to take the kittens to this nursing mom for you.
