I'm desperate for homes for kittens...they are outside cats and we have 16 living under our deck..?

We have 3 little ones only about 8-10 wks old...they are darling kitties, 2 gray and white we call Pixie and Dixie (Unfortunately Dixie is a male)...and Puffer an all black beautiful ball of fur..None are tame but we could probably catch them in a trap we have if someone would come get them...I worry about them with this frigid Iowa weather....
