Cystitis in cats is a very common disease that affects the lower urinary tract , especially the bladder. It is much more frequently seen in cats that eat only dry food , in obese animals , and in those that live in stressful or unpredictable home environments . For your feline friend to continue living a completely normal life, it's necessary to make changes both in the home and in their diet, and of course, follow the veterinarian's instructions. If only medication is administered without addressing the factors that contributed to the problem, the treatment will not be as effective as it should be, and the cystitis is more likely to become recurrent or chronic.
So, how do you treat cystitis in cats? Before focusing on treatment, it's crucial to understand what it is, its causes, symptoms, and possible complications.
What is cystitis?
Cystitis is a disease that causes inflammation of the urinary bladder . It is part of what is known as feline lower urinary tract disease (FLUTD), a group of disorders that cause discomfort when urinating. This inflammation can be caused by multiple factors: stress , bladder cancer , bacterial infection , urinary crystals or stones , obesity , or metabolic disorders such as diabetes or kidney disease. It is also very common for a clear cause not to be identified, in which case it is called feline idiopathic cystitis , where chronic stress and certain neurological and hormonal imbalances play a significant role.
In all cases, the clinical consequences are very similar. A cat with cystitis will experience pain when urinating , lick its genital area more than usual, and may urinate outside its litter box , even in unusual places like the bed or next to its food bowl. Furthermore, it is very common for the cat to urinate frequently but in small amounts, and the urine may contain drops of blood , visible or detectable only in a urine test.
When our furry friend shows these symptoms, it's important to take them to the vet with a fresh urine sample so they can confirm the diagnosis and start treatment as soon as possible. Cystitis itself is usually manageable, but if a urethral obstruction occurs , especially in males, the situation becomes a life-threatening emergency requiring immediate attention.
Most common causes of cystitis in cats
The causes of cystitis in cats can be broadly divided into infectious and non-infectious . Understanding them helps prevent relapses and allows for more targeted treatment.
- Bacterial infectionsBacteria from the external area of ​​the urinary tract (penis or vagina) can ascend to the bladder and cause infection and inflammation of its wall. Less frequently, bacteria arrive via the bloodstream from other infectious sites in the body. They are more common in older cats or with diseases such as diabetes, renal insufficiency o hyperthyroidism.
- Urinary crystals and stones: alterations in the urine pH And the composition of the diet promotes the formation of crystals (especially struvite and calcium oxalate) that irritate the bladder or clump together to form stones. These can cause pain, inflammation, and even total or partial obstruction of the urethra.
- Feline idiopathic cystitisVery common in indoor, neutered cats with some degree of environmental stress. No specific pathogen is identified, but rather a sterile inflammation related to a abnormal stress response, which involves changes in the nervous system and in the hormonal axis that regulates this response.
- Neoplasms (bladder cancer): less frequent, but more serious, it produces inflammation, blood in the urine and other systemic signs.
- Predisposing factors: the obesity, Sedentary lifestyle, the low water intakeAn inadequate diet rich in certain minerals, sudden changes in diet or environment, the arrival of new animals or people, and conflicts between cats in the house increase the risk of suffering from cystitis.
Symptoms and warning signs of feline cystitis
The clinical signs of feline cystitis can worsen over time if not treated promptly. Some of the most common symptoms are:
- Pain when urinatingwhich many cats express with intense meowing or complaints while they are in the sandbox.
- Increased frequency of urinationexpelling very little each time.
- Visible effort when urinating, adopting uncomfortable postures or staying on the tray for a long time.
- Continuous licking of the genital areaas an attempt to alleviate the discomfort.
- Urinating outside the sandboxeven in beds, sofas, or other unusual areas.
- Blood in the urine (hematuria), sometimes visible to the naked eye and at other times only detectable through analysis.
- Behavior changesThe cat may show more nervous, irritableapathetic or with loss of appetiteIn some cases there is fever and general malaise.
If your cat is unable to urinate even a few drops, or makes repeated unsuccessful attempts in the litter box, you should take them to the emergency vet immediately. They could have a urethral obstruction , a condition that seriously endangers their health and can be fatal if not cleared quickly.
Diagnosing cystitis in cats
If cystitis is suspected, the veterinarian will first take a detailed medical history (anamnesis), asking about the frequency of urination, changes in behavior, diet, possible stressful situations, and previous illnesses. Next, they will perform a general examination and a specific assessment of the urinary tract.
It is very helpful to bring a fresh urine sample , collected as hygienically as possible. The litter box should be thoroughly cleaned, and the usual litter can be replaced with special urine collection products. The sample should be kept in a clean container, preferably refrigerated, until you arrive at the clinic. In other cases, the urine is obtained by catheterization or ultrasound-guided bladder puncture , which reduces the risk of bacterial contamination.
This sample is used to perform different tests :
- Urine analysis: measures the Density, pHThe presence of proteins, glucose, inflammatory cells, crystals and bacteria. It may include a test strip and microscopic examination.
- Urine cultureIf bacterial infection is suspected, the urine is cultured to identify the type of bacteria and determine what antibiotics are more effective.
- Blood Tests: allows you to assess the overall status in the cat, detect systemic inflammation and check the renal function or other underlying pathologies.
- Ultrasound and X-raysThey help visualize the bladder and kidneys, and detect calculations, bladder wall thickening, polyps, tumors or anatomical malformations.
With all this information, the veterinarian will be able to differentiate between idiopathic cystitis , urinary tract infection, the presence of crystals or stones, and other less frequent causes, thus adjusting the treatment.
How is cystitis treated in cats?
To treat the disease, it is necessary to act on several fronts, combining pharmacological treatment , changes in diet , improvement of the environment and stress control.
- PharmacotherapyThe professional may recommend treating it with anti-inflammatory for about 7 or 10 days, analgesics to relieve pain and, in some cases, a smooth muscle relaxant to reduce spasms when urinating. If a bacterial infection, will be added antibiotics Specific treatments are based on the culture results. When crystals or stones are present, it may be necessary to use medications that modify the pH of the urine or even resort to a surgical intervention if the stones are large or cause obstruction.
- Home treatment and supportive measuresIf we have a feline that has been diagnosed with cystitis, we will have to make sure that, first of all, it is an animal happy and not very stressedand that we are giving it a quality food (preferably grain-free and with a good proportion of animal protein). If this isn't the case, it will be very important to make these changes: start giving it a meal, if possible wet, containing mainly carne and a low percentage of vegetables, increase the water intake with fountains or several drinking troughs distributed throughout the house, and dedicate all the time and attention possible ways to make him feel calmer. In cats prone to cystitis, the veterinarian may recommend specific urinary diets and supplements such as glucosamines or certain nutraceuticals to protect the bladder mucosa.
In addition, it's essential to maintain the litter box's hygiene , provide a stress-free environment with high places, scratching posts, and safe havens, and avoid punishing your cat if it urinates outside the box, as this will only increase its anxiety. Good physical condition, moderate exercise, regular veterinary checkups, and proper hydration are fundamental pillars for reducing the risk of recurrent cystitis episodes and protecting long-term urinary health.
