Your pee smelling like cat pee usually means it's concentrated (dehydration), has ammonia due to diet (high protein), or indicates an underlying issue like a UTI, kidney stones, or liver/kidney problems. The strong, pungent smell comes from concentrated urea or bacteria, so drinking more water often helps, but if it persists with pain, frequent urination, or cloudy urine, see a doctor.
If you detect a hint of ammonia in your urine, it could be a sign of a urinary tract infection (UTI). The odor suggests that bacteria may be swimming around in your urinary system, most likely in your urethra, kidneys or bladder. Urine showing signs of a UTI may also be cloudy or even a bit bloody.
The groin is a hotspot for sweat glands (apocrine glands), and sweat contains compounds like urea, also found in urine. If sweat or a small amount of urine gets trapped in your underwear or on your skin, bacteria can break it down, creating an ammonia odor.
Some women describe their menopause body odour as smelling like urine, and even cat pee, which could be caused by excess ammonia due to increased amounts of apocrine sweat.
Some of those metabolites--especially certain thiols and amines--can smell urinous or ammonia-like, reminiscent of cat urine. Poor hygiene, infrequent washing of clothes, or limited air circulation increases bacterial growth and intensifies the smell.
Multiple things can cause your house to smell like cat urine, even if you don't have a cat. Investigate if there is mold, leaking Freon, sewer gases, smelly plants, spoiled food, or even stains from previous pet owners.
Urine might have an ammonia smell due to eating certain foods, a urinary tract infection, a liver or kidney problem, or dehydration.
So, the reason stress sweat smells worse than other sweat is because different glands react to stress than react to heat and exertion. These glands produce a kind of sweat that is full of food for bacteria, and bacterial growth leads to odor.
A person with kidney failure may have breath that smells like ammonia or urine. Serious liver disease can make breath smell musty or like garlic and rotten eggs.
It's possible the smell you're detecting isn't cat pee. Things like mold and mildew, ammonia-based cleaners, and decaying food can also give off a smell similar to cat urine. If the scent is persistent and it's not obvious where or if your cat peed, it may be worth considering other causes of the scent.
When the kidneys aren't functioning properly, they can't effectively remove toxins and waste, including urea. Urea is a byproduct of protein metabolism that is normally excreted in urine. If it builds up in the bloodstream, it can break down into ammonia and be released through the breath, causing the distinctive odor.
The most common reason for a vagina to smell like ammonia is often related to urine, particularly if there is residual urine on the skin or underwear, which can happen due to improper wiping or slight incontinence. This ammonia-like odor can also be influenced by dietary factors, dehydration, or bacterial overgrowth.

If the enzyme is missing or its activity is reduced because of a variant in the FMO3 gene, trimethylamine is not processed properly and can build up in the body. As excess trimethylamine is released in a person's sweat, urine, and breath, it causes the odor characteristic of trimethylaminuria.
A strong fishy smell in cat urine can be a sign of a urinary tract infection, which are common in cats. A strong fruity or sweet urine smell can signal feline diabetes. A stronger ammonia smell can signal even more concentrated urine, which can be due to kidney disease.
Conditions like kidney disease, diabetes or hyperhidrosis can affect how your body processes waste, leading to an intense ammonia smell. It's essential to tune into your body's signals and consult with a healthcare professional if you suspect your sweat's scent is more than just a dietary or exercise-related quirk.
If your kidneys aren't working properly, you may notice one or more of the following signs:
Foul-smelling urine may be due to bacteria. Sweet-smelling urine may be a sign of uncontrolled diabetes or a rare disease of metabolism. Liver disease and certain metabolic disorders may cause musty-smelling urine.
Caring for Your Kidney
If you detect a hint of ammonia in your urine, it could be a sign of a urinary tract infection (UTI). The odor suggests that bacteria may be swimming around in your urinary system, most likely in your urethra, kidneys or bladder. Urine showing signs of a UTI may also be cloudy or even a bit bloody.
