P.G.
Tasha-
I have used baking soda. Where the accident happened wet the carpet a bit and clean up what you can. After you are through cleaning up the worst of the problem sprinkle baking soda on the damp area. Let it sit for a while till the rest of the carpet dries then vacuum up. You may have to brush the carpet a little. This should leave the carpet clean and the odor gone. This has worked for me.
