Pet urine is possibly one of the world's most disgusting things likely to end up on your favourite asian rug. It is yellow in colour, watery in consistency, and when as little as a few hours old, smells worse than anything as readily available on the planet.

But bear in mind, humans are afraid of cat wee. From the days of early man recognising the smell of tiger urine frightening them, we all have a fear of cat urine. So be brave! It is not a substance to be meddled with.

Armed with a bucket of suds and a mop, travel your house and thoroughly clean any hotspots for cats to use as their toilet. These include corners, toilets, rugs, and anything which you think might (to the cat) smell like urine.

Keep their litter tray spotlessly clean! Kitty's stop using their litter tray when it gets all too much for them, and transfer to a new toilet spot. Telling them "NO!" isnt going to help, but as long as the litter tray is clean, and so is the rest of the house, they should select the tray to do their business in.

Make sure they know not to wee around the house! Train them as you would a dog - worked for me!  

It is amazing just how many people I speak to about this do not discover their cat urine until AFTER the ideal window of opportunity for cleaning it. Typically, pet urine is at its most cleanable any time up to about three hours after its deposit. After that, you have a helluva job on your hands. In fact, if the urine is hunted down when fresh, it can be cleaned up (with the knowledge in step three) with the greatest of ease. Any later, and it will linger there for a very long while, and cleaning it efficiently is not a task for the faint hearted.

So, every day when coming home from work, or in the morning, or after the time your cat is most likely to wee in your house, take a walk around. Sniff. Look for any tell-tale damp patches - the sooner you hunt for these stains, the better.  

Now, this is tricky bit, and cannot rely on simply man-power alone. Cat urine is a vicious substance. You will need chemicals, and depening on the cat's diet, bleach will simply not be enough. I used to concoct my own mixture, however now use this pet stain remover which works wonders with wee washing.

The basic SI principle of purifying cat-weed areas is "Use the strongest chemicals you can, but not strong enough to wreck the surface. So, if you have a deep blue carpet, hydrogen peroxide probably is not the best thing to use. Sure, it will work wonders with your wee stain, but will probably turn your prized carpet white. I learnt that one the hard way.

Also, do not be afraid of scrubbing. It will help to remove pet stains, as well as any molecular traces of the urine from tiny fibres and niches.
