What a beautiful little orange girl you are. I am so very thankful that your family found you and took you all in. I am with Jim on keeping animals contained. I have several outside enclosures so mine can go out, but they can't run off. One is just a large dog kennel that I have put a roof on. There are many different cage type things you can buy nowdays, please consider one of them. The Mother of these babies probably didn't "abandon" them. Very seldom does that happen. Unless you actually saw the Mother around the area and just ignoring the kittens, something bad probably happened to her. This is the case with most street animals, they don't last long. The poor outside Mommas do the best they can for their babies, but they can't reason, so they don't always recognize danger. But happy COTD to you and your sibbys, and I pray you have many happy years with your family. God Bless you all.
