Upper respiratory infections cost $50-$100 for exam, $100-$400 for treatment. Feline herpesvirus and calicivirus cause most cases. Healthy cats usually recover, but kittens and immunocompromised cats risk serious complications. Herpesvirus is lifelong with potential flare-ups.
What Causes Upper Respiratory Infections
Feline herpesvirus (FHV-1) and calicivirus (FCV) cause 80-90% of cases. Spread via direct contact, sneezing, contaminated surfaces. Bacterial co-infections (Chlamydia, Bordetella, Mycoplasma) can follow. Multi-cat environments have higher rates.
Symptoms What to Watch For
Sneezing + runny nose are the classic signs. Also: watery eyes, congestion, mouth breathing, appetite loss, fever, lethargy. Calicivirus adds mouth ulcers and drooling. Kittens may develop eye ulcers.
Diagnosis $50-$200
Physical exam ($50-$100) usually sufficient - symptoms distinctive. PCR testing ($100-$200) identifies virus if needed. Chest X-rays ($150-$250) if pneumonia suspected. Blood work ($100-$200) for severe cases. Average $50-$200.
Treatment $100-$400
Supportive care: keep cat eating/drinking comfortably. Antibiotics ($30-$60) for secondary infections. Antiviral drops/lysine ($20-$40). Anti-inflammatory/pain meds ($20-$40). Severe cases with hospitalization $500-$1,500. Average $100-$400.
Total Cost $150-$600
Mild cases: $100-$300. Severe cases with complications: $500-$1,500 including hospitalization.
Risk Factor Kittens and Senior Cats
Flat-faced breeds (Persians, Himalayans) are more susceptible due to narrowed airways. Siamese and Scottish Folds also at higher risk.
Recovery 1-3 Weeks
Most healthy cats recover in 7-21 days. Kittens and immunocompromised cats take longer. Herpesvirus remains dormant for life with potential flare-ups.
Prevention Vaccination
Core FVRCP vaccine protects against herpesvirus and calicivirus. Keep new cats isolated for 2 weeks. Vaccination is the best prevention.

Insurance Traps
A common infection that can recur - here's how insurance handles it.
URI Coverage Basics Waiting period
Most policies cover URI diagnosis and treatment. Standard 14-day waiting period applies. Vet exams, meds, diagnostics, and hospitalization typically covered.
The Chronic Herpesvirus Pre-Existing Trap Pre-existing
One documented URI denies all future claims as pre-existing. Since herpesvirus is lifelong, a single episode can block coverage for all flare-ups. Enroll before symptoms appear.
Simple vs. Complicated URI Costs Coverage
Simple URIs: $100-$400. Complicated cases (pneumonia, eye ulcers, hospitalization): $500-$1,500. Insurance best for severe complications. Recurring flare-ups add up.
Vaccination Requirements Coverage
Some policies require current FVRCP vaccination. Unvaccinated cats may have claims denied as preventable. Keep records up to date.
Common Questions
Real answers about costs, treatment, and insurance coverage.
What are the symptoms of a URI in cats?
Sneezing (first sign), runny nose, watery eyes, congestion, appetite loss, fever, lethargy. Calicivirus adds mouth ulcers and drooling. Kittens may develop eye ulcers. Recovery: 1-3 weeks in healthy cats.
How much does it cost to treat a URI in cats?
Simple URI: $100-$400 (exam, antibiotics, meds). PCR testing: $100-$200. Complicated cases (hospitalization, pneumonia): $500-$1,500. Herpesvirus eye ulcers may need specialist care.
Are cat upper respiratory infections contagious to humans?
Feline herpesvirus and calicivirus are species-specific, not human-contagious. Chlamydia felis rarely causes mild eye inflammation in immunocompromised people. URIs are highly contagious between cats - isolate infected cats and wash hands after handling.
Do cats carry herpesvirus for life?
Yes. FHV-1 remains dormant in nerve cells, reactivating during stress or illness. Flare-ups cause sneezing, eye discharge, congestion. Stress reduction, lysine supplementation, and good health reduce recurrence frequency and severity.
When should I take my cat to the vet for a cold?
See a vet if: no eating for 24 hours, mouth-breathing, thick green/yellow discharge, very lethargic, eye squinting, or ulcers. No improvement in 7-10 days: vet visit. Kittens, seniors, FIV/FeLV cats need prompt care with any respiratory symptoms.
Can I prevent my cat from getting a URI?
FVRCP vaccine protects against the two most common causes. Vaccination reduces severity/duration, not infection completely. Isolate new cats 2 weeks. Reduce stress in multi-cat homes. Good hygiene and ventilation prevent spread.
How long does a cat URI last?
Healthy cats: 7-21 days. Sneezing/discharge peak days 3-5, then improve. Kittens and immunocompromised cats take longer with higher complication risk. Symptoms beyond 2-3 weeks or worsening: vet visit, secondary bacterial infection possible.
Does pet insurance cover URI treatment in cats?
Most policies cover URI diagnosis and treatment (exams, meds, hospitalization). Critical: enroll before symptoms appear. One documented URI denies all future respiratory claims as pre-existing. Some policies require current vaccinations.
My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
