Query: Horrible! Will only bring trouble to your home!

This stuff is evil! I bought it because my cat was scared of the construction going on at my home, thought it might calm her down. She had never done anything wrong or bad, she was the perfect cat, just a little scared by all the commotion. I plugged the stuff into the outlet, and my cat, my female cat mind you, PEED all over it! She peed all over the area actually! It has to be SEVERELY bad for my cat to do something like that! She has never gone near that part of the house since then, even though I removed it and cleaned up immediately!
