The Ragamuffin screening plan has four tracks and one shared clock: an echocardiogram at 12 months and every 12 months after, a sleeping respiratory rate counted at home 3 nights a week, a weigh-in on the first of every month, and a hairball count that matters more than most owners think. Feline coronavirus exposure is common and mostly harmless, so a positive titer is not a diagnosis and should never drive a decision on its own. Screen for what changes management: heart wall thickness, body condition, and the difference between a hairball and an obstruction.
The calendar, with prices
Most practitioners accept the schedule below for a clinically normal adult. Cut every interval in half if a parent or sibling had heart disease, and keep all reports in one folder, because wall thickness is read as a trend across 3 or more studies.
| Age | Screen | Repeat (months) | Typical cost (USD) |
|---|---|---|---|
| 12 mo | Echocardiogram plus blood pressure | 12 | 200-380 |
| 12 mo | HCM variant panel, if the line is known | once | 120-200 |
| 12 mo | Body condition score and weigh-in | 1 | 0-40 |
| 24 mo | Urinalysis plus urine culture if sediment is active | 12 | 55-110 |
| 36 mo | Chemistry, T4, fructosamine | 12 | 95-170 |
| 48 mo | Abdominal radiograph if vomiting repeats | as needed | 90-180 |
Heart: what an echo actually measures
Hypertrophic cardiomyopathy thickens the left ventricular wall and stiffens the filling phase; a cat can carry it for years with a normal exam. Ask for the actual measurements, not the word normal: interventricular septum and free wall thickness in millimeters at end-diastole, the left atrial to aortic ratio, and the diastolic function note. A wall at 5.0-5.9 mm in a cat with a murmur is watched at 6 months; 6.0 mm and above moves to a cardiology review and a 3-6 month echo interval. Murmurs are graded 1-6, and grade does not track severity, so a 2/6 murmur with a 1.9 left atrial to aortic ratio outranks a loud 4/6 with normal ratios. A validated HCM variant test exists for some lines, not all: a negative result lowers risk and never clears the cat, so the echo stays on the calendar either way.
FIP: monitoring, not fortune telling
Feline coronavirus infects many cats, mutates in a small minority, and produces feline infectious peritonitis when it does. An antibody titer tells you exposure, not protection and not risk, so do not pay for it as a screening test. What earns its cost is pattern recognition: fever that sits at 103-105 F for more than 5 days and does not answer to a first antibiotic, weight loss of 5% in 30 days, a distended abdomen with a fluid wave, or a cloudy anterior chamber. Confirmation leans on fluid analysis, the Rivalta test, imaging, and sometimes PCR on fluid or tissue. Antiviral treatment is a nucleoside analog class drug given under veterinary supervision for a fixed number of weeks; it is by veterinary prescription only, and self-sourcing it is both illegal in most jurisdictions and a common cause of relapse.
Weight and glucose: the 9-point score
Score body condition on the 1-9 scale monthly: ribs felt with light pressure at 5, a visible waist from above at 5, and a tuck at 5. A Ragamuffin at 7 or above gets a measured ration, not a free feeder. Weigh on the same scale at the same hour, log it, and aim for 1-2% of body weight lost per week, never more; faster loss in a heavy cat is a recipe for hepatic lipidosis. Bloodwork from age 3 includes glucose and fructosamine, because stress hyperglycemia is common in clinic and fructosamine separates it from real diabetes. Insulin is by veterinary prescription only, dosed by weight, and adjusted only against a glucose curve.
Hairballs, and the mass that is not one
Two hairballs a month in a long-coated cat is grooming, not disease; 4 or more, or any hairball with food in it, points to overgrooming or delayed gastric emptying. Brush 3 times a week for 5 minutes, and daily in shed season, which for most households means 6-8 weeks twice a year. Hairball pastes are a laxative class product, short-term only, and by veterinary advice. A true trichobezoar presents differently: vomiting that becomes daily, 24-48 hours without stool, a painful firm abdomen, and an appetite that drops to zero. That combination is an imaging case, not a hairball case, and surgery is sometimes the answer.
Four signals worth logging weekly
- Sleeping respiratory rate: count breaths for 30 seconds while the cat is asleep, multiply by 2, 3 nights a week. Above 30 per minute on 3 days in a row is a call.
- Weight: monthly, to 0.1 lb. A 5% drop over 30 days is the single most useful number you own.
- Abdomen: a soft tape measure around the widest point every 2 weeks; 2 cm of gain without weight gain is fluid until proven otherwise.
- Grooming: 10 minutes of observation once a week, counting barbered patches and hair in the stool.
Hour-level thresholds
Numbers here are triage, not diagnosis. They decide whether you drive now or book a slot.
| Signal | Threshold | Act within |
|---|---|---|
| Open-mouth breathing or blue tongue | Any, at rest | 0 h, go now |
| Pulse at home | Above 220 per minute at rest | 1 h |
| Urine output | No urine for 12 h with a full bladder | 2 h |
| Vomiting | 3 times in 12 h, or any with blood | 4 h |
| Fever | Above 105 F, or 103 F for 5 days | 24 h |
What the year costs
Year 1 with an echo, a variant panel, and 2 wellness visits runs 450-750 USD. Routine years settle near 300-520 USD. A cardiology consult is 200-400 USD, an abdominal ultrasound 250-450 USD, a radiograph set 90-180 USD, and an FIP workup with fluid analysis 300-600 USD. An antiviral course is the one line that can reach four figures, which is why the free sleeping respiratory rate matters. Weighing trends against a chart such as /health/health-cat-weight-trend-chart/ makes the 5% rule obvious instead of arguable.
Twelve months, five moves
- Book the 12-month echo with blood pressure in the same 45-minute visit, and ask for printed measurements.
- Start the sleeping respiratory rate log tonight, 3 nights a week, for 4 weeks to get a baseline.
- Set a phone reminder for the 1st of each month: weigh, score body condition, photograph the waist from above.
- Fix a grooming day, twice weekly, and add a 10-minute coat check in the two shed seasons.
- At the 12-month review, compare wall thickness and left atrial ratio to baseline before agreeing to the next interval.
The echo protocol and the questions to ask before sedation are laid out for a larger breed at /health/breed-maine-coon-heart-screen/. For anything the cat might have eaten, from a lily to a dropped pill, check /tools/toxic/ before you wait for symptoms.

Frequently asked
Is a positive coronavirus titer a reason to worry?
No. A positive titer means the cat has met feline coronavirus, which is common and usually harmless, and it does not predict which cats will develop feline infectious peritonitis. Spend the money on pattern recognition instead: a fever above 103 F lasting 5 days, 5% weight loss in 30 days, a fluid wave in the abdomen, or a cloudy eye. Those findings, not the titer, decide whether imaging and fluid analysis are needed.
How often should a Ragamuffin have an echocardiogram?
First at 12 months, then every 12 months, with the interval cut to 6 months if wall thickness measures 5.0-5.9 mm, and to 3-6 months with a cardiology review once it reaches 6.0 mm or the left atrial to aortic ratio rises. Ask for the printed numbers each time, because a single normal report is far less useful than three measurements plotted together.
When is a hairball an emergency rather than grooming?
Two hairballs a month in a long-coated cat is normal grooming output. Four or more, daily vomiting, 24-48 hours without stool, a firm painful abdomen, or an appetite that falls to zero point to a trichobezoar or another obstruction, and that combination needs imaging the same day rather than a hairball paste and a wait.
