I have little advice about the house, but for the cat a mixture of 1 quart hydrogen peroxide with 1/4 cup baking soda and just a few drops of liquid dish soap works well for removing most of the smell. It will need to SOAK on the cat before rinsing. (sorry that I don't know the metric conversions, but just think a large bottle of peroxide and a small amount of baking soda...it does not need to be exact)
