They are adorable!
I, too, agree the mother should be fixed, but I know two families who have a whole bunch of farm cats that aren't fixed. Every other days its like I hear news about a new litter being born. When I go over to one of their houses, we play a game of "try to find and tame the wild kittens" Its fun, catching the little kittens and naming them. I'll try to bring my camera next time.
