I'm so glad you're introducing them to the outside slowly, and with harnesses. Kittens are so unpredictable that I could just see one of them running off and giving you all sorts of grief until you found it again. But they really looked like they were enjoying themselves! And it's great that you got in the pic. Now you have a picture of yourself with them when they are kittens. Trust me, you will be happy you got that picture when they are older.
