Dear /an/

This my little kitty Luna. I've had many cats in my life, but never kittens this young (we think she's 6 months). Lately she's been getting into EVERYTHING. She has 3 toys that she used to love, but now she's more interested in playing with things she knows she shouldn't. She's a very smart cat, and she knows when she's doing something wrong. I tell her no, and have a little spray water bottle. Is there anything else I could do?
