Dear MOby,

After a party at a new friend’s house last weekend, I decided to do the right thing and slept on the couch instead of riding home slightly inebriated. As punishment for that good deed, when I woke up early the next morning to make good my escape, I noticed an inescapable and pervasive odor wafting up into my helmet as I began to ride off. I managed to shrug it off as I was riding home, but when I stopped and removed my favorite old Vanson jacket, there it was again – cat pee! And plenty of it. I’ve tried a couple of cleaners but the memory of that night refuses to leave my jacket. What can I do to get rid of it? Will it go away over time? Help me…

Dear Olaf,

My former cat, Bob, tried to warn me off my first ex wife by performing the same operation in her nice leather jacket very early in our relationship. This was a fashion-weight ladies’ garment that wasn’t going to put up with a lot of harsh chemicals and things, but it was also thrift-store and no great loss. Still, my ex seized upon the opportunity to get a new jacket after chastising Bob and me at length about the old one. After we were married, anytime there was unpleasantness, after things cooled down Bob would often give me that look from his end of the couch: See? I tried to warn you man.

Before we go any further, look inward and ask yourself if the feline in your story (most certainly a fellow male), was simply trying to offer you some good relationship advice?

If your jacket is truly soiled, don’t waste your time or money on any of the stuff they sell at pet stores to remove odors. Even if your old Vanson is up to it, the smell will live on to some degree. What you want is a professional cleaner, specifically one that offers Ozone cleaning.

Ozone, (O3), sometimes called “activated oxygen”, contains three atoms of oxygen rather than the two atoms we normally breathe. Ozone is the second most powerful sterilant in the world and can be used to destroy bacteria, viruses and odors. Interestingly ozone occurs quite readily in nature, most often as a result of lightning strikes that occur during thunderstorms. In fact the “fresh, clean, spring rain” smell that we notice after a storm most often results from nature’s creation of ozone. However, we are probably most familiar with ozone from reading about the “ozone layer” that circles the planet above the earth’s atmosphere. Here ozone is created by the sun’s ultraviolet rays. This ozone serves to protect us from the ultraviolet radiation (rather than to deodorize a rain of cosmic cat pee from the heavens -ed.).

While ozone is very powerful, it has a very short life-cycle. When contaminants such as odors, bacteria or viruses make contact with ozone, they are destroyed completely by oxidation. In so doing, that extra atom of oxygen is consumed and there is nothing left…no odor…no bacteria…no extra atom, only oxygen. Ozone reverts back to oxygen after it is used.”

Ozone generators are placed in houses that have had fires or floods to get rid of the smell. You can buy an ozone generator like this one to remove odors from your entire dwelling, but if all you’ve got is a jacket, a quick google search for a dry cleaner that offers ozone cleaning should fix you right up. They’re going to clean your jacket first, then hang it up in a chamber with an ozone generator in it. Should do the trick. Good luck with the cat.

    Cat pissed on my favorite riding jacket once. Cleaned it 409, then odorban, then got a can of the most headrush inducing shoe polish I could find and treated it. No more smell after that. Now I always hang up my jacket anywhere there are cats.

  • Mad4TheCrest

    My dentist uses an ozone generator to disinfect gums after his usual bloody poking and drilling. Maybe next time I can ask for a freebie Jacket demusking? (I have a crotchety old cat who gets pissy about nearly everything)

    • DickRuble

      Time for you to find an honest dentist.

      • Steve Clark

        I would say another cat or just get rid of this one, a trip to the “farm”.

  • SRMark

    Cat got my helmet once. Woof. Helmet went in the trash.


      yep that’s just too close

  • DickRuble

    It won’t work. A waste of money. Ditch the old jacket/helmet/garment, ditch the cat (and the wife if she insists on the cat) and get a new jacket.

    • Vrooom

      I have to say I had a cat pee on a lady friends coat, and the drycleaning got the smell out. No idea whether they used the ozone of not, but it doesn’t smell.

    • Steve Clark

      “and the wife if she insists on the cat”, well think about it.

  • StripleStrom

    We had a devil cat that would pee in the toaster any time we left him for more than a day. Little bastard wouldn’t leave a drop of evidence, but you sure knew when you made toast!

    • Eric

      Now that’s funny. My cat (RIP) used to sit on the old answering machine on/off button, and the machine would repeatedly say “answer functions are on…answer functions are off…answer functions are on…” any time we left him alone, or if he just wanted attention. Way less stinky than that! He did steal ALL of the kitchen towels out of the drawer from time to time, though. Funny bastard; I still miss him.

    One third white vinegar, two thirds warm water in a spray bottle. Spray area generously. Wipe off excess. Can take a couple of treatments, but NONE of the commercial anti urine treatments really worked. This did.


      and it works for the type of mold that frequents leather;used the same thing on my holsters and slings; i heard tomato juice for skunks

  • John B.

    Life is too short to ride around smelling like cat piss… even a little. Buy a new jacket! Shit happens… so does piss (apparently).

    • Rocky Stonepebble

      Get rid of the cat.

      • Tinwoods

        Idiots like you just hate cats.

        • Rocky Stonepebble

          OK, dearie.

  • Nice photos! But who names a cat Bob?


      someone with a sense of humor! or the owner of a bobcat…

      • Rocky Stonepebble

        A Mercury Bobcat. It’s a feisty critter that picks up the litter, it’s a Bobcat, the Mercury Bobcat. Available at the sign of the cat.

        • Sayyed Bashir

          Mercury is out of business.

          • Rocky Stonepebble


          • Sayyed Bashir

            It is not available at the sign of the cat. Actually the sign of the cat is not there anymore.

    • Wally

      Hey! MY cat’s name is Bob.

  • Old MOron

    Just wear it. The smell will go away. In the mean time, it’ll remind you of a good night.

  • kenneth_moore

    Why the lead photo of Stoner at Phillips Island? Its a great shot but I don’t see the connection.
