Can anyone connect me with someone who could take in a "park" mother
cat with her 4-5 kittens (5 days old)?

Try http://www.kittenrescue.org What color are the kittens? Long or short hair?
If they're real pretty with longer fur, it'll be much easier to find them
homes. I personally don't care about looks but others do. I'm full up with baby
squirrels right now or I'd take them in to foster.
