Urinary Tract Infections in Cats - Symptoms, Causes, Diagnosis, Treatment, Recovery, Management, Cost
What are Urinary Tract Infections?
Sometimes, urinary tract conditions can be associated with other diseases, including chronic kidney disease and hyperthyroidism. However, in many cases, there doesn’t seem to be an underlying cause at all – in this case, the technical diagnosis would be “feline idiopathic cystitis” (FIC).
Feline lower urinary tract disease, or FLUTD, is the umbrella term for urinary tract conditions in cats.  A feline urinary tract infection (UTI) is typically characterized by painful and difficult urination. Urinary tract infections in cats can range from mild to fatal, so it is important that you consult a vet right away if you suspect your cat is suffering from a UTI.

Symptoms of Urinary Tract Infections in Cats
Cats are notorious for hiding their symptoms from their owners. But if you suspect your cat may have a UTI, it is imperative that you don’t ignore it. If your cat is exhibiting any these symptoms, consult a vet immediately. An ignored UTI can lead to a urethral blockage, which can be fatal.
  • Difficulty urinating
  • Urinating outside of the litter box
  • Yowling while urinating
  • Frequent grooming of the genitals
  • Excessive urinating with little or no urine
  • Swollen penis
  • Gritty particles on the penis
Causes of Urinary Tract Infections in Cats
The cause of UTI in cats can be difficult to pinpoint, particularly if the cat does not suffer from any type of bladder or kidney disease. This means that the bladder is inflamed, but there is no easily identifiable reason as to why. About 65% of cats who suffer from UTI and other urinary tract conditions are diagnosed with FIC.
Despite that, there are suspected causes of FIC:
  • Defects in the lining of the bladder
  • Inflammation of neurogenic structures in the bladder wall
  • Stress levels and abnormal reactions to stress
However, urinary tract infections in cats are often associated with other diseases of the bladder:
  • Urolithiasis: stones present in the bladder
  • Urethral obstruction: blockage of the urethra in male cats-- a severe condition
  • Bacterial infections: typically uncommon, usually prevalent in older cats
  • Neoplasia: tumor present in the bladder or urethra
Diagnosis of Urinary Tract Infections in Cats
Cystocentesis
Your vet may collect a sample of your cat’s urine , called cystocentesis. This process will involve inserting a needle directly into the bladder to collect an uncontaminated sample of urine. In order to reach an accurate diagnosis, the urine must be free from contaminants found in the environment.
The urine may be sent to a lab to allow for cultures to grow. This way, the vet can see the specific type of bacteria present in your cat’s urine, which will aid with diagnosis and treatment.
Basic Urinalysis
The urinalysis will reveal the amount of blood present in the urine, as well as the urine’s pH balance, glucose, and protein levels. The vet will then analyze the urine using a microscope, looking for bacteria and uroliths, or stones in the urinary tract.
X-Ray
Your vet may perform an X-Ray on your cat in addition to the urine culture and urinalysis. Any crystals or stones in the bladder will show up on an X-Ray.
Treatment of Urinary Tract Infections in Cats
One important part of treating a UTI is increasing your cat’s water intake. For general cases of FLUTD, treatment will vary based on the cause of the infection.
Urolithiasis
Surgery is sometimes required to remove stones from the bladder. A change in diet may help dissolve certain types of bladder stones. If this is possible, your vet will prescribe a special diet that will help break up the stones and keep them from coming back.
Urethral Plugs
Urethral plugs must be removed right away, as they can cause kidney failure in as little as 2-3 days. In this case, your cat will be administered anesthetic and the vet will remove the blockage. Because your cat will have a urinary catheter after this procedure, your cat will be kept overnight or even for a few days.  Your vet may prescribe painkillers and a special diet to help prevent blockages from coming back.
Bacterial Infection
This type of infection, typically clears up easily with the use of antibiotics. The vet will determine which type of drug to prescribe based on the type of bacteria present in the urine.
Neoplasia (Tumors)
Unfortunately, by the time symptoms start to appear, neoplasia will likely already be at an advanced stage, making removal of the tumor impossible. Fortunately, though, this disease is quite rare in cats, and usually affects older cats. Chemotherapy treatment might help manage the tumor’s size. Your vet may also prescribe NSAID pain relievers, which can reduce tumor inflammation. 
FIC
There are many options when it comes to treating FIC. One way to relieve symptoms of FIC is by increasing your cat’s water intake. Switch dry food to wet, canned food. You will also want to ensure that your cat is not under high amounts of stress.

Recovery of Urinary Tract Infections in Cats
Your cat’s recovery will depend on the underlying cause of the infection. Generally, cats will start to show improvement within 2-3 days of treatment, if the case is not serious.
Always follow your vet’s treatment instructions. Be sure to provide clean water at all times. Encourage drinking where you can and ensure that litter boxes are clean. This can help reduce your cat’s stress and may speed up recovery.

Thank you for your question. I apologize for the delay in my reply, this venue is not set up for urgent emails. Cats can develop bone and joint disease as they age, and It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get any testing or treatment taken care of that might be needed.

My pet has the following symptoms:
Abdomen Pain
Fever
My 3 year old cat started acting lethargic, refused to eat or drink, had a fever, and was being extra careful walking and jumping. We took him to the vet and he has a UTI. He was given a shot of long acting antibiotic, an nsaid, and sent us home with two more nsaids for the next two days. She said he should be back to normal today, however, he is still acting like he doesn’t feel good and has been hiding under the kitchen sink all day. Should we be worried or give the medicine more time to work?

My pet has the following symptoms:
Frequent Urination
My cat seemed to have a UTI. I brought her in the Dr. couldn’t take a urine sample but gave her amoxicillin. She’s been on it for three days but is still peeing little quarter sized pees. She doesn’t seem to be in pain. But she does go in the box frequent but not as frequent. Should I take her back in for tests after the medication is finished or should I take her back in tomorrow? I don’t want the medicine to mess up testing?

My pet has the following symptoms:
Pinkish Urine
My cat is about 8 years old and in the last 1.5 years she keeps developing UTIs. I have taken her to the vet multiple times and they give her antibiotics and pain relief which helps but a few months pass and it comes back again. She has a pinkish urine and strains to pee/takes a long time but she is peeing which is a relief it’s not blocked. We got a few extra tests done last time and everything was quite normal so I don’t know why she keeps developing them. She does live with 2 Male cats but she seems to keep to herself most of time. Do you think they could be causing her stress. I’ve tried different diets aswell, always comes back. Is there any else I can do to prevent her from getting them. I hate seeing her in pain.

My pet has the following symptoms:
Blood In Urine
My 7 year old female barn cat has had blood in her urine for a few months. About 6 weeks ago her appetite declined. We have had her urine tested and the vet put her on an antibiotic, but it didn't clear up the blood. He put her on a second, more powerful antibiotic and it did help for about a week, but the blood has returned. Her appetite is now good and she acts fine, but the blood is still there. Her urine looks like red wine. The vet also did a culture and sensitivity test on my cat's urine (needle into the bladder) and the culture was negative. The blood is still in her urine. Xrays show no bladder stones. The vet says an ultrasound would be the next option, but that it is possible that even that test will not show anything. My understand that some things just can't be explained, but I want to be sure I am doing all I can for her. She is a great barn cat. What would you suggest?
