What is Pus in the Urine?

Pus in the urine in cats, or pyuria, is not an illness or disease in itself, but rather a clinical symptom of present health conditions. Pus in the urine is caused by an infection of bacteria, fungus, or yeast found somewhere in the upper or lower urinary tract system of the feline. The pus itself is a combination of white blood cells and proteins sent from the feline’s immune system to fight off the bacterial infection. The presence of pus in the urine is caused by noninfectious or infectious pathological processes that causes cell damage, inflammation, and an elevated immune response. Pus in the urine in cats is a sign that a feline is suffering from a severe infection that can only be diagnosed by a veterinary professional.

If you noticed that your cat’s urine has a strong odor and is cloudy in appearance, she may have pus in the urine. The change in the urine itself may be the only symptom a cat owner notices, as pus in the urine in cats is not a disease or illness, but a symptom of a larger condition at hand. A cat that has pus in his or her urine is an indication of an infection, as the pus itself is an abnormally large accumulation of white blood cells. The immune system only releases extra white blood cells when an infection is detected. Common causes of pus in the urine in cats could be a bladder infection, kidney infection, or infection of the reproductive organs.

Symptoms of Pus in the Urine in Cats

Pyuria is a symptom in itself and can be noted by urine with a strong, or foul odor paired with a cloudy appearance. Symptoms that often accompany pyuria have to do with the dominant feline health condition. Common symptoms seen in cats with pus in the urine can include: 

  • Cloudy urine
  • Fever 
  • Pain during urination
  • Dehydration 
  • Foul-smelling urine 
  • Polyuria (frequent need to urinate) 
  • Straining to pass urine
  • Polydipsia (increased water intake) 
  • Inflamed vaginal or penile external organs 
  • White or yellowish discharge 
  • Redness of the urinary tissues
  • Inability to urinate
  • Depression

Causes of Pus in the Urine in Cats

There are many causes for pus in the urine in cats. Since pus is evidence of white blood cells released to destroy foreign elements that are attacking the body, pus in the urine is caused by infections in the upper or lower urinary tract system. The kidneys, ureters, urinary bladder, and urethra, which are the main organs of the urinary system, could be infected by a species of bacteria or fungi. Stones can also affect these urinary organs and can be the underlying cause for the presence of  urinary pus. Additionally, the reproductive organs in females can also develop an infection (pyometra) with pyuria being the main symptom. Trauma or the development of a tumor can affect all of these urinary organs, and in turn, cause pus to be present in the urine of a cat.

Diagnosis of Pus in the Urine in Cats

As pus in the urine in cats is a symptom and is not a diagnostic illness, the veterinarian will find pyuria in his/her diagnostic proceedings. The examination of urine, known as a urinalysis, is the common process through which a vet may detect pyuria. Upon examination of the urine, the doctor may note the presence of neutrophils (white blood cells) to be of a higher concentration and a urine culture may be requested. A urine culture is a laboratory test that will allow the particles of infectious material to grow in order to detect what type of material is attacking the cat’s urinary system. The vet may also x-ray or scan the bladder.

Treatment of Pus in the Urine in Cats

The treatment of pus in the urine in cats is based on the condition the veterinarian found during diagnostics. Administration of an oral antibiotic is a common treatment method used with the presence of pus in the urine. The culture test that pinpointed which strain of bacteria is causing the problem will determine which type of antibiotic the vet will prescribe. Intravenous fluids may also be given to your cat to reverse dehydration and encourage urination to further eliminate the infection from the body. For some, a bladder supplements and urinary supportive diet will be started.

Recovery of Pus in the Urine in Cats

The prognosis for pus in the urine in cats lies dependent on the dominant health condition the feline was diagnosed with. Cats with bacterial, fungal, or yeast infections have a very positive prognosis as aggressive treatments usually correct this common urinary health problem. If the your veterinary noted the presence of a tumor, your cat may not have as good of a prognosis depending on its location and on how long the tumor has been allowed to manifest in the current location.

Thank you for your question. It is possible that Jasmine has a urinary tract infection if you are noticing white debris where she pees. It would be best to have her seen by a veterinarian, as they can look at her urine and see if treatment will help get her back to normal again. I hope that she is okay!

My pet has the following symptoms:
Green Pee, Weak, Not Eating
My small kitten of 2 1/2 months if extremely weak at this point and won’t eat anything. However when I went to check on her she was peeing a light green color. This is extremely concerning because she has nearly eaten anything. What does it mean?

The presence of green coloured urine is concerning and may be an indicator of liver disease with increased concentrations of bilirubin in the bloodstream; other causes may be due to diet or medication side effects. You should visit your Veterinarian for a thorough examination, urinalysis and a blood test to help narrow in on a diagnosis. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Pus In Urine
My cat is a male just turning a year, recently he would not eat his dry food at all 2 days went by, he was vomiting and then i noticed he was not going to the bathroom at all. I kept monitoring that and noticed he had pus in his urine. I googled it and read to try to give him moist food and add a teaspoon of apple cider vinegar. I know i should have taken him to the vet but really can not afford too so i did the home remedy and he has eaten the moist food with the vinegar and hes going to the bathroom still pus but not as much. I guess my question is is it possible for this to be working? Need professional advice.

I think it is highly unlikely that Bailey will have this problem get better without veterinary care, honestly. Male cats are prone to urinary blockages, and many urinary problems are related to diet. A urinary blockage can be a terrible, painful condition, and it would be best to have him seen by a veterinarian, have his urine looked at, and get antibiotics and a urinary diet if needed, earlier rather than later. You may be able to keep him from having problems long term with a little bit of intervention now. Many clinics offer free or discounted first exams, and there may be a low cost clinic near you. I hope that all goes well for him!

My pet has the following symptoms:
Discharge
We have a 14 day old kitten that the stray cat momma abandoned 7 days ago. We have been stimulating her to poop and pee via a warm washcloth and it has been working well. However, yesterday and this morning I have noticed a pus-like raindrop sized goo on her urethra first thing in the morning that I have to clean off. Her urine besides that is clear. But the goo made me worried about a possible UTI especially because there is a possibility of cross contamination with her poo. We try to keep it as clean as possible. Changing tissues multiple times per cleaning while she is pooping. Should she be taken to the vet? She is still urinating well.

It certainly sounds like Shiloh has a vaginal infection which certainly may occur if your are using a washcloth to stimulate defecation and urination; this is something you should see a Veterinarian about so that the diagnosis may be confirmed and treated. Infections in kittens can be serious if not treated promptly due to their immature immune systems. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Depressed
Not Himsel
Jelly In Urine
My cat as been odd this past few days, I am not sure if it is an infection because he does'nt have the same symptoms that a cat with infection should have like my searches on internet. Yesterday I have notice he peed a jelly transparant substance. He still walks, drinks a little water, but he is not like him self. He does'nt play anymore, he does'nt even come for his daily treats and won't eat them.I am not shure if he eats because I have 2 other cats so it is hard to tell if he goes and have a little bite I try to watch him as closely as possible but during the day we work and I am not there to watch him. He does'nt groom himself anymore, he really looks depressed. Probably because he is in pain but there is no blood in the urine and he does'nt lick his genitals like cats would with an infection. He does'nt cry either when he pees. Tonignt I will try soft canned food, I made some reseach and found out that this is one of the first steps to take and will give im a little sider vinegar to help boost is immune system. I do not have money for a vet check up, so if you have any recomendations or advices to give me it will really be apreciated!!
