Cystitis in cats

Written by Animonda | Jan 15, 2026 3:18:17 PM

A bladder infection (=cystitis) in cats can have many causes and can be very painful. In contrast to a urinary tract infection, in which the bladder, kidneys and urinary tract are affected, a bladder infection only affects the bladder. Find out everything you need to know about symptoms, medication, home remedies, healing time and diet.

Symptoms of bladder infection in cats

Many cats have to deal with a bladder infection at least once during their lifetime, as there are many different causes that can lead to this condition. If you suspect that your cat is suffering from cystitis, a visit tothe vet is always advisable. Do not wait to see if it gets better on its own, as complications are possible if it is pushed out. It is better to have your cat checked if the following symptoms indicate a bladder infection:

  • Frequent urination
  • Wailing sounds when urinating
  • Relatively small amounts of urine
  • Blood in the urine
  • Intense odor
  • Puddles of urine in the home
  • Uncontrolled loss of urine
  • Licking of the genitals
  • Hunched back when urinating
  • exhaustion
  • reluctance to eat

These symptoms can occur either individually or in combination. If cystitis is not recognized and treated in time, it can become chronic, which manifests itself as follows

  • Fever
  • unwillingness to eat
  • vomiting
  • weight loss
  • movement disorders


Cause of cystitis

Some diseases have a typical trigger. This is not the case with cystitis. There are various possible causes. Some are medically plausible, but sometimes the trigger cannot be identified. In this case, veterinarians speak of "idiopathic cystitis". Of course, it is better to know the cause so that it can be treated specifically and, if possible, eliminated for the future. If the vet is unable to make a clear medical diagnosis, the pet owner may be able to provide crucial information.

Possible causes of cystitis in cats:

Compared to cats, male cats suffer from cystitis more frequently. This is partly due to the fact that their urethra is narrower, and partly because they display a particularly territorial behavior and therefore clash more frequently with males, which is associated with stress.

What to do if your cat has a bladder infection?

Only a vet can determine with certainty whether a cat has cystitis or whether it is another illness with similar symptoms. You should therefore always consult a vet if you suspect this. Otherwise there is a risk that the cat will experience more and more pain when urinating.

It can also lead to extreme dilation of the bladder and damage to the kidneys. Therefore, do not wait too long to see if the situation improves over time. It is better to make an early appointment with the vet for a check-up.


What medication is given to cats with cystitis?

The choice of medication depends on what the vet finds. A fresh urine sample is a great help here. As this is difficult to obtain quickly at the vet's surgery, or only with a great deal of effort, it is up to the pet owner. You may be able to collect some urine at home in a ladle, bowl or cup.

You can also soak up a stain with a pipette or temporarily fill the litter tray with non-absorbent cat litter or cover the cat litter with cling film. Then tilt the tray so that you can collect the urine in a container. In any case, it is important to take the urine sample to the vet within the next few hours.

If the vet has a urine sample, he can examineit for any crystals and bacteria it may contain. This may already lead to a quick result, but a blood test and ultrasound may also be necessary. Depending on the findings, the following medication may be used to treat cystitis:

  • Antibiotics to combat a bacterial infection
  • Pain-relieving medication
  • Supplements or dietary feed
  • Antispasmodic medication
  • Measures against crystals in the urine
  • Surgical intervention due to blocked urinary tract


What home remedies help with cystitis?

Home remedies can only have a supportive effect. The pain and possible consequences of cystitis should not be underestimated, which is why a visit to the vet should always be planned. In addition to taking medication, teas (camomile, horsetail) are typical household remedies. These are known for their anti-inflammatory and diuretic effects. Boil it as usual and offer it to the cat when completely cooled. There are also special teas for cats on the market.

How long does it take to heal from cystitis?

If a cat is given antibiotics and painkillers for a bladder infection caused by bacteria, the healing process usually only takes a few days. Improvement often occurs after just one day. However, do not be tempted to stop taking an antibiotic early. Give it for the entire period agreed with the vet to minimize the risk of resistant bacteria developing.

If the cause of cystitis is not bacteria but struvite stones, for example, treatment may take several weeks.

How can cystitis be prevented in the future?

The cause of the bladder inflammation is crucial:

  1. Immune system
    A weak immune system can increase the risk of bladder inflammation. This could be triggered by poor quality food. Therefore, make sure that you always provide your cat with high-quality food. If your cat drinks too little, this can also be one of the causes of a bladder infection - for example, by promoting the formation of stones in the urine. It is then advisable to offer several and different water points in the home and to avoid feeding dry food without exception. Alternate between wet and dry food or give your pet wet food instead. If it turns out that urinary stones were the cause of the bladder inflammation, you can use a special food against urinary stones. This helps to get the pH value of the urine under control.
  2. Hygiene
    If the cause of the bladder infection was a bacterial infection, review the hygiene conditions in your home: does each cat have its own litter tray and are these always cleaned sufficiently? You should always remove excrement immediately, change cat litter at regular intervals and wash the bowl with hot water. This also applies to the food and water bowls.
  3. Stress
    Psychological stress can be a cause of cystitis that should not be underestimated. This could be caused by another cat, a dog or pushy children. Insufficient space to retreat, restlessness at the food bowl or litter tray can also cause stress for a cat. You should eliminate these and other stress factors to minimize the risk of chronic cystitis.
