12 days old - Rescued from a Trash Can

Somebody threw these little ones in the trash can.  We are not certain how long they were there, in the heat, in the garbage.  When they were rescued they reeked of urine and, well, rotten food.  They have had three baths in the last 24 hours and still they smell.  I think the smell is coming from inside.  To survive, perhaps they were consuming each others urine and feces causing havoc on their digestive system.  They have not yet fully realized they don't need to do this anymore, so for awhile they will be close together, but separated into different cat carriers.  Hoping and praying this stops the nasty habit.
At 12 days old they need to be stimulated to go to the bathroom, so for a few more days, access to a litter box isn't needed.  They took to a bottle right away.  That sure makes feedings go much quicker than with a dropper.  Last night they ate at 11pm, 2am, 5am, 8am and it will continuing around the clock like this for the next week.  Each feeding session takes an hour at this point.  There is eating, cleaning or bath, stimulating, and changing the bedding, along with a little snuggle time.  They wear out quick, and go right back to sleep.  Now, if only I could go right back to sleep.
We are thinking of names.  The black and white one is a boy.  The gray ones are girls.
