Bacterial Cystitis in Cats
While quiet common in Dogs, bacterial infection of the bladder, or bacterial cystitis, is not seen as frequently in cats. Unfortunately, that means it’s often overlooked in cats altogether and/or mistreated.
What are the symptoms of bacterial cystitis in cats?
Symptoms associated with a bacterial cystitis can include:
- Hematuria (blood in the urine that may or may not be seen in a litter pan)
- Stranguria (straining and/or discomfort on urination)
- Pollakiuria (increased frequency of urination/trips outside or to the litter pan with typically smaller volumes)
- Incontinence/accidents (urinating in inappropriate places)
- Discomfort (evidenced by restlessness, abdominal pain, crying or excess grooming)
Some of these signs will be easy to recognize in an indoor cat that uses a litter pan, but more challenging in a cat that goes outside since we don’t tend to walk our cats outdoors and aren’t typically standing on top of them when they urinate.

Sometimes, there will be no symptoms whatsoever. In this case, you may only realize the infection exists if your veterinarian is doing routine screening tests or running tests for some other unrelated complaint.
Is my cat at risk of bacterial cystitis?
Bacterial cystitis occurs when bacteria find their way into the otherwise sterile environment of the bladder/urinary tract. There are certain circumstances that can increase your cat’s risk of developing a bladder infection including:
- The presence of bladder stones, crystals, polyps or tumors that can cause irritation and harbor bacteria
- An underlying medical condition, such as, feline leukemia virus, feline immunodeficiency virus, diabetes mellitus, hyperthyroidism, and chronic kidney disease
Can anything else cause cystitis?
Yes, other things can. The term cystitis only refers to any inflammation in the bladder. In bacterial cystitis that inflammation is due to a bacterial infection. However, bacterial cystitis accounts for only a small fraction of all feline cystitis cases—only 1-3% according to Alleice Summers, DVM. In her book, Common Diseases of Companion Animals, Alleice also outlines a study run at Ohio State. During this study 132 cats were examined specifically for symptoms of cystitis and 61% of them were found to have something called idiopathic cystitis –not a bacterial infection.
How do you confirm and treat bacterial cystitis?
A urine culture will help your veterinarian determine if your cat
