A cat with a runny nose and a sneezing fit usually leaves the clinic with 2 drug classes, a 10 to 14 day schedule, and a bill between 80 and 300. The drugs are not the expensive part. The exam and the recheck are, and those 2 lines are also the 2 lines you can plan around. Below are the 6 numbers that make up the total, what pushes a 300 bill past 400, and where owners quietly pay twice for the same 14 days.
Why a URI course splits into 2 drug classes
Roughly 80 to 90 percent of feline upper respiratory cases trace back to herpesvirus (FHV-1) or calicivirus (FCV), and neither responds to an antibiotic. Antibiotics are added for a secondary bacterial infection, which looks like thick yellow or green nasal discharge, a fever above 39.5 C, or no improvement after 5 to 7 days of supportive care.
The second class is an antiviral, in practice famciclovir, used when FHV-1 is suspected: repeated sneezing cycles, corneal ulcers, or 2 or more flare-ups in 12 months. Antiviral courses run 10 to 14 days in most protocols and 21 days when the eye is involved. The 2 classes do different jobs, 1 kills bacteria and 1 cuts viral shedding, and about 60 percent of mild cases need only the first. That single fact is worth 40 to 105 on the final bill.
The 10 to 14 day clock, day by day
Day 0 is the exam and, in roughly 1 case in 3, a PCR panel. Days 1 to 5 are the part you control: food intake, 10 minutes of steam in the bathroom twice a day, wiping discharge 2 to 3 times daily, and a room at 20 to 24 C with no drafts. Day 5 to 7 is the decision point. If the discharge is still thick and green, the antibiotic choice or dose is wrong, and switching costs another 25 to 60.
Day 10 to 14 closes the course and holds the recheck. Stopping on day 5 because the cat looks bright is the most common reason a 14 day course gets paid for twice: the 14 day supply costs 20 to 55, and a relapse adds the same amount plus a second exam at 30 to 50.
What the course costs in 3 regions
The table prices a moderate case, meaning 1 exam, both drug classes, and 1 recheck. Figures are in local currency and rounded to the nearest 5. A single-drug course with no recheck is the 80 end of the band; the 300 end is a US two-drug course with a recheck.
| Line item | United States (USD) | United Kingdom (GBP) | China (CNY) |
|---|---|---|---|
| Exam and URI workup | 60–90 | 40–60 | 120–250 |
| Antibiotic, 10–14 days | 20–55 | 15–40 | 50–120 |
| Antiviral, 10–14 days | 40–105 | 30–75 | 80–220 |
| Recheck at day 10–14 | 30–50 | 22–40 | 60–130 |
| Total, both drug classes | 150–300 | 107–215 | 310–720 |
| Total, antibiotic only | 80–145 | 55–100 | 230–500 |
Read the rows, not the total. The exam plus the recheck is 90 to 140 in the US, 62 to 100 in the UK and 180 to 380 in China, against 80 to 145, 55 to 100 and 230 to 500 for the antibiotic-only course: the visits cost roughly what the drugs do. The cheapest realistic saving is therefore not a cheaper tablet, it is skipping a visit you do not need and keeping the ones you do.
What pushes a 300 bill past 400
Four add-ons do most of the damage. A respiratory PCR panel runs 120 to 250 and changes the plan in maybe 1 case in 4. Hospitalisation with nebulisation and oxygen runs 60 to 120 per day, and a kitten that will not eat for 48 hours often needs 2 days. An appetite stimulant plus a 7 day supply of a second antibiotic adds 35 to 90. A dental or eye referral, when the ulcer is deep, adds 90 to 180.
Cats that go past 400 usually share 1 of 2 histories: a kitten under 8 weeks old, or a cat that had 3 or more flare-ups in the past year. Both justify the spend. A 4 year old indoor cat with clear discharge and a normal appetite rarely does.
Where owners overspend without noticing
Three habits inflate the total. Filling a 30 day bottle when the course is 14 days wastes 40 to 55 percent of the drug and leaves a half-used bottle that gets used later at the wrong dose. Splitting tablets to stretch a supply is worse: it produces a sub-therapeutic dose, which is how resistance starts. Buying online saves 20 to 30 percent but adds 3 to 5 days of shipping, and a URI that waits 5 days often ends up needing the 120 to 250 panel it might otherwise have skipped.
The pet insurance detail that catches people: most policies exclude respiratory disease for the first 14 days of cover, which is exactly the length of a standard course. Sign-up before the cat sneezes, not after.
Cheaper course, same 14 days: 5 steps
- Ask for an itemised written estimate before the first dose, and ask which of the 2 drug classes is actually indicated today.
- Fill exactly 14 days, no more, and ask for the smallest tablet size that matches the dose so nothing is split.
- Book the recheck for day 10 rather than day 14, so a switch still fits inside the course.
- Run the steam and wipe routine twice daily for the full 10 days; it costs nothing and cuts the odds of a second visit.
- Keep every receipt: 3 visits in 12 months is the point where insurance pays for itself.
Compare that with the yearly upkeep of a healthy adult cat in our flea treatment cost breakdown, where 12 months of prevention often costs less than 1 URI course. If the mouth is the problem instead, the dental resorption cost guide uses the same line-item method, and you can model your own total in the cost calculator.
When cost should not decide
Three findings end the budget discussion. Open-mouth breathing or a blue tinge on the gums is an emergency, not a 14 day plan. A kitten under 8 weeks that stops eating for 24 hours can dehydrate inside 12 more. A fever above 40 C in a cat that sits head down and refuses food needs the visit today, whatever the estimate says. Everything else on this page can wait for a weekday appointment, which is 20 to 35 cheaper than an emergency slot in all 3 regions.
What the 80 to 300 number leaves out
It excludes 2 costs that show up later. A cat that carries FHV-1 will flare again: 40 to 60 percent do so within 12 months, usually after a move, a new pet, or a boarder stay, and each flare costs 60 to 120 if it is caught early. It also excludes the 15 to 40 you will spend on a second litter box, an air filter refill, or a humidifier that reduces how often the next course happens. Budget 100 to 150 a year for a known carrier and the surprises stop being surprises.

Frequently asked
Is 80 to 300 a realistic total, or just the medication?
It covers the medication in most cases and the whole course in the cheaper regions. A 10 to 14 day supply of both drug classes runs 60 to 160 depending on the country, so 80 is a single-drug course with no recheck and 300 is a two-drug course with an exam and a recheck. Add a PCR panel at 120 to 250 if your vet orders one.
Can I finish a 14 day course early once the sneezing stops?
No. Sneezing usually stops around day 5 to 7 while the tissue is still healing, and stopping there is the most common cause of a relapse that costs another 20 to 55 in drugs plus 30 to 50 for a second exam. If side effects are the reason, call and ask for a switch instead of stopping.
Does the antiviral always have to be part of the plan?
No. About 60 percent of mild cases need only an antibiotic, or nothing at all beyond steam and fluids. Famciclovir is worth its 40 to 105 when herpesvirus is likely: repeated flare-ups, corneal ulcers, or 2 or more episodes in 12 months. Ask your vet which of the 2 classes the exam actually supports.
