The review is in: i used rrosenberry's concoction for pee smell on my carpet ( So you get the idea: Toby has had accident on the carpet on and off since we got him and NOTHING helped, he was potty trained and then he rebelled i guess, and started peing EVERYWHERE...... As soon as you walked into our apartment the smell was a little nauseating it was REALLY BAD and NOTHING helped.....) I am going to go back and spray again in a few days because one bottle was enough to do the whole area that is peed on....but i just wanted to say THANK YOU THANK YOU THANK YOU THANK YOU....... IT WORKED, it smells a little like hydrogen peroxide (that will go away) BUT NO MORE PEE SMELL!!!!! I also took someone elses suggestion and mixed teh downy with the water and sprayed it on my carpets and now not only is the pee smell gone, it SMELLS WONDERFULL and the downy made the carpet SOFTER TO WALK ON (was that supposed to happen????? you didnt mention this side efect in youre post....... not that im complaining).... Thank you all for youre suggestions and help
