<human>: Can you provide a brief rundown of the text in within 3 sentences?

I have never owned a cat before but for some time I have had a porch cat that spends her time between outside and in my garage (I have a crawl space under my house that leads into the garage where I keep her food) and she had kittens 5 weeks ago.  There are four of them and I noticed yesterday that two of them have figured out how to follow her outside of the garage and the other two were just crying in my garage wandering aimlessly.  I haven't seen the mother since.  I brought them inside and they seem to be enjoying it for the most part and enjoy cuddling up on the couch with me and exploring the house.  I have an empty bedroom where I set up a box with a blanket in it for them to sleep last night.  I have a 5 year old pit bull who has been more than excited they are here.  She has always enjoyed cats but they don't tend to enjoy her.  She is obviously big and plays rougher than they tend to prefer.  I introduced them yesterday and today (here is a [photo] of one of their first encounters after knowing she wouldn't eat them) and she just wants to lick all over them and follow them around and cries when I separate them so the babies can get some space from a giant dog in their faces.  I fed them the same food that their mother was eating (Diamond dry food) and one seemed to have an easier time eating it than the other.  I am just kind of at a loss about this and would love some insight.
<bot>: I have NO clue how to care for kittens or how to successfully integrate them to my dog without her harassing them or hurting them accidentally.
