There are just way to many horror stories for outside kitties! One time is all it takes to make you wish you had never done it and then it's too late. Supervised and on a leash is the only way to be sure and keep your cat safe. My goal is one day to have an outside enclosure for the kitties so they can be outside but still safe.
Time and spaying will calm your baby down. She's just an energetic little one. Enjoy it now because one day you will miss all her activity!!
