In fact, the smell hasn’t gone anywhere. You’ve simply become desensitized to it. When you’re exposed to a smell for a long period of time, the neurons involved with your olfactory systems eventually stop transmitting the signal.

That’s why you’ll meet people who will swear blind that their cats are mysteriously odour-free, even when you can smell a strong odour of cat urine any time you enter their homes. This can be frustrating and embarrassing for the house-proud cat owner.

The only thing worse than having a persistent smell in your home that you can’t get rid of is a smell that you can’t detect and your visitors can.

Conventional cleaners often fail to deal with the issue. It’s particularly bad when carpets or soft furnishings are involved, as they absorb the odour and make it very hard to get rid of.

Even hard but porous surfaces, like unsealed wooden floors or certain types of linoleum, can soak up the smell and resist all efforts to scrub it away.

When I was a first-time cat owner, I would return to the scene of the crime over and over again, scrubbing with every product I could think of and getting absolutely nowhere.

Why Does Cat Urine Smell?

Cat urine contains a variety of bad-smelling compounds. The main offender is ammonia. Like all animals, a cat’s urine contains urea; this is an odourless substance, but it breaks down into ammonia when it’s exposed to air.

Ammonia has a very strong and very unpleasant smell, and since cat urine is fairly concentrated, there’s a lot of it present.

There are other compounds involved as well. Male cats concentrate testosterone in their urine, giving it a more pungent smell.

A cat’s spray is a combination of urine and certain pheromones that cats and other animals can detect. Regrettably, it also smells strongly to humans. In the wild, feral cats use this strong-smelling spray to mark their turf.

There are various conditions that can exacerbate the problem. Dehydration can make the problem worse, since it makes the urine more concentrated.

Urinary tract infections can produce a lot of additional odour — as well as making accidents outside the litter-box more likely.

The result of all this is a collection of very distressing smells that can make being a cat owner more challenging than it needs to be be.

Enzymatic cleaners, as the name suggests, contain enzymes. These are compounds that facilitate chemical reactions, by binding to molecules in specific ways.

In living creatures, enzymes are important in many biological processes. In cleaning, they’re important for getting rid of odours and stains that get left behind by conventional cleaning products.

My recommendation is to look for a product that’s specifically intended for use on pet accidents. You’ll find plenty in your local pet store, and a few in larger supermarkets too.

You can also try Googling: “cat urine removal from carpet”, “cat urine odor removal”, “remove cat pee smell” or ” cat pee cleaner”.

Check that the product is certified for use on soft furnishings and carpets before you apply it, and maybe try a little out on an unobtrusive area. If the affected item is something you can machine wash, try running it through your machine with a biological laundry detergent.

These also contain enzymes and are very good at getting rid of the smell of cat urine.

Inappropriate urination can have many causes. If your cat is still young or you’ve just got her, she may simply not be properly housetrained yet.

Cats may have accidents outside the litter-box if there’s another cat in the household that stops her from using it. Some cats can get very fussy about who gets to use “their” box. As a rule, you’ll a litter-box for each cat plus one extra. Yes, that’s a lot of boxes to have around; it’s still better than cleaning up cat wee.

Urinary and bladder infections can cause cats to miss the litter-box on occasion. If the cat is suffering from pain and discomfort, she may even urinate on a chair or a bed.

This isn’t spiteful or wilfully destructive. She’s seeking the comfort of a familiar spot to help her cope with the distress that comes with urination.

I know this isn’t much help when you’re tossing out a favourite cushion, but it’s really not her fault. Treating the illness can help with problem behaviour. My British Shorthair had this issue.

As with most British Shorthair cats, he’s normally great about using the box; when he started having accidents, I knew something was wrong. A course of medicine from the vet soon had him back to his normal fastidious self.
