UTI in Cats: Symptoms, Treatment, Cost (2026 Guide)
Urinary tract infections (UTIs) cause painful, frequent urination in cats. Symptoms include blood in urine, straining in the litter box, and accidents outside the box. Requires antibiotics - cannot resolve on its own.
Your cat is making repeated trips to the litter box, straining, and producing only drops of bloody urine - these are signs of a urinary tract problem that needs immediate veterinary attention. Here's how to recognize UTIs, what treatment involves, and the critical difference between infection and blockage.
Has your cat had urinary issues?
Track urinalysis results and UTI episodes over time. Know if your cat is at risk for recurring infections.
Track My Cat's Urinary HealthWhat Is a UTI in Cats?
A urinary tract infection (UTI) occurs when bacteria (most commonly E. coli) invade the bladder or urethra, causing inflammation and pain. However, true bacterial UTIs are actually less common in cats than in dogs. Most cats with urinary symptoms have a condition called FLUTD (Feline Lower Urinary Tract Disease), which includes UTIs, bladder stones, crystals, and idiopathic cystitis (inflammation without infection).
FLUTD Categories:
- Bacterial Infection (15-20%): Actual UTI requiring antibiotics
- Urinary Crystals/Stones (15-20%): Struvite or calcium oxalate crystals
- Idiopathic Cystitis (55-65%): Bladder inflammation without infection - most common
- Urethral Obstruction (<10%): Blockage preventing urination - EMERGENCY
Symptoms of UTI in Cats
🚨 Common UTI Symptoms
Classic Signs:
- • Straining to urinate (looks like constipation)
- • Frequent trips to litter box with little/no urine
- • Blood in urine (pink, red, or brown urine)
- • Crying or meowing during urination
- • Urinating outside the litter box
- • Strong-smelling urine
- • Excessive licking of genital area
🚑 EMERGENCY - Go to ER Immediately:
- • Male cat cannot urinate at all (blockage - fatal within 24-48 hours)
- • Straining with NO urine produced
- • Swollen, hard, painful abdomen
- • Crying in pain, hiding
- • Vomiting, lethargy, loss of appetite
- • Weakness or collapse
⚠️ Urinary blockage is a life-threatening emergency. Do NOT wait until morning.

UTI vs. Urinary Blockage: Critical Difference
| Feature | UTI/Cystitis | Urinary Blockage |
|---|---|---|
| Who Gets It | Any cat, more common in females | Almost exclusively MALE cats |
| Can They Urinate? | Yes - small frequent amounts | NO urine at all |
| Urgency | Vet visit within 24 hours | EMERGENCY - GO NOW |
| Outcome if Untreated | Worsens, kidney damage possible | Death within 24-72 hours |
| Treatment Cost | $150-400 | $1,000-3,000 |
How UTIs Are Diagnosed
Diagnostic Tests
- • Urinalysis: Checks for bacteria, blood, crystals, white blood cells. Most important test.
- • Urine Culture & Sensitivity: Identifies specific bacteria and best antibiotic (takes 3-5 days). Done if UTI suspected or doesn't respond to initial treatment.
- • Bloodwork: Checks kidney function (see cat kidney values guide), especially if chronic UTIs
- • X-rays or Ultrasound: Checks for bladder stones, tumors, or anatomical abnormalities
Typical Urinalysis Findings in UTI
- • Bacteria present
- • High white blood cells (WBCs) - indicates inflammation/infection
- • Red blood cells - blood in urine
- • Elevated pH (often >7.0)
- • Crystals may be present (struvite common with UTI)
- • Protein in urine

Antibiotics
Common Antibiotics for Cat UTIs:
- • Amoxicillin/Clavamox: First-line choice, broad spectrum. 7-14 days.
- • Enrofloxacin (Baytril): Fluoroquinolone, effective but more expensive. 7-10 days.
- • Cephalexin: Alternative if allergic to amoxicillin. 10-14 days.
- • Trimethoprim-sulfa: Older option, still used for resistant infections.
- • Convenia (injection): Single injection, lasts 14 days. Good for cats who resist oral meds.
⚠️ CRITICAL: Complete the entire antibiotic course even if symptoms improve after 2-3 days. Stopping early causes resistant infections.
Additional Treatments
- • Pain Medication: Buprenorphine or gabapentin for discomfort
- • Anti-Spasmodics: Prazosin to relax bladder/urethra
- • Urinary Acidifiers: May help prevent crystal formation
- • Increased Water Intake: Wet food, water fountains, flavored water
- • Special Diet: Prescription urinary diet (c/d, s/o) if crystals present
- • Stress Reduction: Feliway diffusers, separate resources if multi-cat home

Recovery Timeline
- Days 1-2: Symptoms may persist. Keep giving antibiotics.
- Days 3-5: Noticeable improvement - less straining, more urine volume, less blood.
- Days 7-10: Symptoms should be resolved. Continue antibiotics as prescribed.
- Day 14: Complete antibiotic course. Recheck urinalysis if symptoms persist.
Prevention Strategies
- • Increase Water Intake: Feed mostly wet food, use water fountains, add water to food
- • Keep Litter Boxes Clean: Scoop daily, 1 box per cat plus one extra
- • Reduce Stress: Minimize changes, use Feliway diffusers, provide hiding spots
- • Maintain Healthy Weight: Obesity increases UTI risk
- • Consider Urinary Diet: Hill's c/d, Royal Canin Urinary SO (especially if history of crystals)
- • Regular Vet Checkups: Annual urinalysis for senior cats (7+)
- • Monitor Litter Box Habits: Catch problems early
Encourage More Water Intake
Many cats prefer moving water over a stagnant bowl. A gravity waterer provides a consistent fresh water supply and can help increase hydration—one of the most important ways to prevent UTIs and urinary crystals.

Risk Factors
Cats at Higher Risk:
- • Senior cats (10+ years) - weakened immune system
- • Diabetic cats (see cat diabetes guide) - sugar in urine promotes bacterial growth
- • Obese cats
- • Cats with kidney disease (see cat kidney values)
- • Male cats (higher blockage risk, though females get UTIs more)
- • Indoor-only cats (less urination frequency)
- • Multi-cat households (stress, competition for litter boxes)
- • Cats with previous UTI/FLUTD history (30-50% recurrence rate)

Common antibiotics include amoxicillin, clavamox, enrofloxacin (Baytril), and cephalexin. Treatment typically lasts 7-14 days. Always complete the full course even if symptoms improve.
Can male cats get UTIs?
Yes, but male cats are more prone to urinary blockage than infection. Male cat urinary issues are emergencies - if your male cat cannot urinate, go to the ER immediately.
