A sweet tiger cub, padding softly on its paws across the ground. A little lion getting its head nuzzled by mama as they soak in the sun. Two young kangaroos--joeys--at play. An infant chimpanzee, clinging lovingly to its mother's back. Nothing's more irresistible than an animal baby, and with these magnificent photos, kids can meet the cutest ones of all, and their families, too.
