I have Anwen in my lap (my blue kitten) and she's sleeping....... :'o)

My fosters have graduated from the bottle to lapping to mashed up solid food
with KMR.  :o)  The local SPCA inspector babysat them on Friday when I was
out of town and fed them in a saucer.  They've been doing that for 3 days.
Today, they started nibbling on my Alsatian's dogroll, so they've got
formula and mashed up kitten food.

They're now eating about every 4-6 hours (KMR with mashed up Whiskas kitten
wet food), but there are times when I have to give them food every 2 hours
because they're still hungry- high, incessant kitten whinging.  They're
quite full when they're done the first time, but are still insisting on food
2 hours later.  I fed them formulae at 9:30 and had to feed them again at
11:30.

Anyone have any ideas?  Should I be feeding them more at one sitting or more
often?  How much kitten food should I be adding to the formulae?

And one more question: seems like none of them have been defecating-
urinating quite a bit tho.  Any thoughts on that?  I saw a poop the first
night I had them and another one today, but none in between.
