see what you need to do is go down to the beach and get yourself some sand
pour two cups of sand into a litre of bleach and stir with a wooden spoon until you get a golden mixture, wrap the remaining sand in a canadian flag and leave it in the garden for two days
apply the golden mixture of sand and bleach to your chest and then jump chest first onto your cat's back when she is least expecting it, for best results, do it while she is eating. the cat will secrete a black liquid from it's nose which you should collect in a jar
take the black liquid and pour it over the canadian flag in which you wrapped the sand, if done correctly you should see smoke emerging from the flag. get down on your hands and knees and crawl backwards in circles around the flag while mourning the death of mac dre. keep doing this until the flag stops smoking.
now, take the sand out of the flag and sprinkle it into the air holes at the top of your ps3, save a spoonful of this sand and gently rub it on the ps3 at the place where the smell is coming from.
your ps3 should now stop smelling of cat piss
hope this helps.
