Urinary Tract Infection in Russian Blues
Urinary tract issues are a significant concern for Russian Blues. Cats can develop bacterial UTIs, feline idiopathic cystitis (stress-related bladder inflammation), and urethral obstruction (life-threatening in males). Russian Blues may show subtle signs — urinating outside the litter box is often the first indicator of a urinary problem, not a behavioral issue.
Prevalence
Common — urinary issues are among the top reasons for vet visits in cats
Typical Onset
Any age; more common in middle-aged to senior individuals
Severity
Mild
Symptoms to Watch For
If your Russian Blue shows any of these signs, monitor closely and consult your veterinarian.
Risk Factors
- •stress and environmental changes
- •inadequate water intake
- •diabetes mellitus (sugar in urine feeds bacteria)
- •male cats at risk for urethral obstruction
- •infrequent urination opportunities
Diagnosis
Urinalysis reveals bacteria, white blood cells, and blood. Urine culture and sensitivity identifies the specific bacteria and which antibiotics will work — always perform before prescribing antibiotics. Cystocentesis (sterile needle collection from bladder) is the gold standard specimen collection method. Imaging (ultrasound/radiographs) rules out bladder stones, tumors, and anatomical abnormalities in recurrent cases.
Treatment
Targeted antibiotic therapy based on culture results (typically 7-14 days). Increased water intake to flush the urinary tract. Follow-up urinalysis after completing antibiotics to confirm resolution. Recurrent UTIs (3+ per year): investigate underlying cause (bladder stones, diabetes, Cushing's, anatomical abnormality). Vulvoplasty for recurrent UTIs caused by recessed vulva.
Prevention
Ensure adequate water intake — provide fresh water, add water to food, consider a pet fountain. Frequent bathroom breaks — don't make pets hold urine for extended periods. Maintain lean body weight (skin folds around vulva trap bacteria). Prompt treatment of underlying conditions (diabetes increases UTI risk). Probiotics may support urinary tract health.
When to See a Vet
See your vet within 1-2 days if you notice straining, blood in urine, or frequent small urinations. EMERGENCY: complete inability to urinate (especially in male cats — urethral obstruction is life-threatening). UTIs are easily treatable but can ascend to the kidneys if neglected.
