  1. I have absolutely NO idea, but I can tell you one thing – my guess is that you are using CHEAP coffee and it WILL SMELL LIKE THAT. You’d be BETTER off buying a BRANDED COFFEE and paying a little extra money. My father used to buy CHEAP coffee and it smelled of DOG. We complained to him at the time, but he STILL bought CHEAP COFFEE, which does have a NASTY smell and that is what you are drinking CHEAP COFFEE. We stopped using it and we eventually just drank still mineral water, which is HEALTHIER for you. My sister got into calling this cheap coffee DOGCOFF.

  2. I had to laugh when I saw this question a few weeks ago. My immediate thought was “the coffee pot and heating system isn’t being cleaned often enough.” With some smugness, I smelled my coffee pot that I clean regularly and it smelled like cat urine after I rinsed it out with hot water, but before I took soap and a brush to it. So rather than leave it there, I’ve been experimenting with cleaning each part of my coffee system almost daily and figuring out ways to put parts in the dishwasher for a thorough cleaning.
    Coffee oils, when fresh, add complexity and depth to a good cup of coffee. I take my coffee seriously and the main reason I switched from Chemex coffee filters to a metal filter was to allow the oils into the coffee brew.
    But when they are allowed to sit for very long, they stink and stick to everything. Even a decent washing and rinse isn’t enough to get rid of them. And while it’s subtle in a fresh cup of coffee, that smell will affect the flavor of the coffee and your enjoyment of it.
    So, wash your coffee making equipment regularly (every 2–3 days or daily if you can) in hot soapy water using a good brush, then wash in the dishwasher if you have that option. The smell should be undetectable…until you forget to wash everything.
    Hope this helps!

  3. My coffee does not smell like cat urine no matter how long I may leave it sitting. I would suggest you change the brand or type of coffee you buy. Or perhaps it is your equipment that needs a more thorough cleaning.

  4. I have never noticed that. Of course since I work nights I’m addicted to coffee. Do you have any cats that might be peeing in your cup? They have remarkable aim. My son had a small soft ball that he annoyed his cat with. Once he left it on the floor. When he picked it up it was saturated with cat piss. He couldn’t believe his fat Pooka bear of a cat had managed to do that.

  5. This is not a generalized experience. Could be the coffee you buy. Could be your cat doesn’t like you. Would suggest you see if if your coffee is old or moldy or just lousy. Would also suggest you test your sense of smell on other scented objects to assess if it might not be you and you sense of smell, in which case you should be evaluated by a neurologist.
