Kittens!!!

This picture is a little fuzzy but if you biggify it and look closely, you can see a white kittie. Boy oh boy, is she cute! She has 3 siblings and a beautiful Mama. We see them almost every day and Mommy wishes we could bring them food and treats...better yet, she wants to bring them home with us. Daddy says that wild kitties should be left alone. (Insert sad face). Have you had any experience with wild kitties? Should we just leave them be or is it ok to bring them some food and treats?
