I just found this because I was seaching for why my six year old daughter is doing this same thing! It's incredibly frustrating. We dont have carpet but its been on blankets pulled off her bed and even in her closet on stuffed animals. It happened months ago but i just went to do laundry and it has happened again. My daughter was diagnosed with ADD and behavioral defiance disorder but when asked why after finally admitting it (blames it on cats- this is human urine not feline) she will make up excuses that are just silly. She is aware of what she is doing as well by why I can not figure out. If you ever found out any information I would love to hear it! ThanksView Thread
