Three numbers cover almost every cat: 3 visits in the first year, 1 visit a year from age 1 to 7, and 1 visit every 6 months from age 7 or 8 onward. That is 3, 1, and 0.5 visits per year, and it is the schedule most feline-only practices actually run. The reason is not ritual. A cat ages roughly 4 cat years to every 1 human year in the first 2 years, then about 4 more per calendar year, so a 10 year old cat is closer to 60 in screening terms, and 6 months of its life is a long interval for kidneys that are already losing function.
The age ladder, with numbers
Use the band the cat is in today, not the one it will reach next year. A 6 year and 11 month old cat is an adult this month and a senior next month.
| Age band | Visits per year | Interval (months) | Visit length (min) | Typical cost (USD) |
|---|---|---|---|---|
| Under 1 year | 3 | 4 | 30-40 | 60-120 |
| 1-6 years | 1 | 12 | 30 | 80-160 |
| 7-9 years | 2 | 6 | 40 | 150-300 |
| 10 years and up | 2-3 | 4-6 | 45 | 200-400 |
Three visits in year 1 land at 8, 12, and 16 weeks of age for the vaccine series, with a fourth at 6 months if the cat was adopted late or the clinic prefers a pre-neuter check. From 1 to 7 years, one annual visit is enough because the 5 core screens rarely move faster than that. From 7 years, 6 months is the interval that catches chronic kidney disease and hyperthyroidism while they are still stage 1 or early stage 2, when the cat looks completely normal at home.
The 5 things a visit should cover
If a clinic weighs the cat and listens to the chest and stops there, you have paid for 2 of the 5. Ask which of the 5 were done before you leave.
| Item | Number it produces | Normal range | Start age (yrs) |
|---|---|---|---|
| Weight and body condition | BCS 1-9, grams gained or lost | BCS 5/9 | 0 |
| Dental and oral exam | Teeth with tartar or resorption, 0-4 stage | Stage 0-1 | 0 |
| Blood panel | Creatinine, BUN, ALT, glucose, T4 | Creatinine 1.6, T4 1.0-4.0 | 1 |
| Urine test | Specific gravity, protein, sediment | 1.035-1.060 | 3 |
| Blood pressure | Systolic, 2 readings 5 minutes apart | 120-160 | 7 |
Two additions are worth paying for on a case-by-case basis: a heart murmur check by auscultation at every visit, and a thyroid panel earlier than 7 years if the cat is losing weight while eating well.
What the 3 kitten visits actually do
At 8 weeks the cat gets a weight, a fecal test, a first vaccine, and a deworming plan. At 12 weeks, the second vaccine, a repeat weight to confirm the growth curve, and a check for retained deciduous teeth. At 16 weeks, the rabies vaccine where required, a third weight, and a conversation about dental home care. The 3 visits are also the only window in which a vet can catch a congenital murmur before it is masked by a thicker chest wall, which is why auscultation at all 3 matters more than the vaccine brand.
Weigh kittens every 2 weeks at home on a kitchen scale; a gain of 100 g per week is typical in the first 4 months, and a flat line for 2 consecutive weeks is a reason to move the next visit forward.
Why adults move to 12 months, then back to 6
From 1 to 6 years the 5 screens are stable enough that annual testing catches change. The two exceptions are weight and mouth. A cat that gains 10% of body weight in 12 months is on a path to insulin resistance, and a cat with a resorptive lesion can lose 5% to 10% of weight in 6 months while eating normally. If either number moves, shorten the interval to 6 months even in a young cat.
At 7 years, the calculus changes. Chronic kidney disease and hyperthyroidism both become common enough that a 12 month gap can mean missing the window where a prescription diet or a thyroid treatment still protects the kidneys. Creatinine can stay inside the reference range until roughly 66% of kidney function is gone, which is why the urine specific gravity and the trend across 2 or 3 visits carry more weight than a single normal result.
What to track between visits
Three home measurements make the 6 month visit far more useful. Weight, once a month on the same scale; resting respiratory rate, counted for 30 seconds at least twice a week, with 40 per minute as the line to call about; and water intake, roughly 40 to 60 ml per kg per day for a normal cat, with a clear rise being an early kidney or thyroid signal. Write them in one place. A trend of 3 numbers beats a memory of how the cat looked last spring.
Body condition is the fourth: score 1 to 9 at home by running a hand along the ribs, with 5 being ideal. A cat at 8 or 9 needs a weight plan before the next visit, not after.
How to make the interval stick
- Book the next visit before leaving the clinic; 6 month reminders get lost, a booked slot does not.
- Put the visit on the same month as a birthday or an annual bill, so it is not a decision each time.
- Keep a single sheet with weight, BCS, creatinine, USG, T4, and systolic pressure for every year.
- For a cat 7 or older, ask for the urine test with the blood panel, not as an optional extra.
- If the cat hates the carrier, leave it out for 3 days before the visit with a worn T-shirt inside.
Recheck intervals after a diagnosis are a different schedule, and the logic for those is in the recheck frequency guide. If weight is the number that keeps moving, chart it rather than eyeball it, using the method in the weight trend chart. Any product the cat licked or ate by accident on the way to the visit belongs in the toxicity lookup first.

Frequently asked
Is one visit a year really enough for a healthy adult cat?
For most cats aged 1 to 7, yes, provided the visit includes all 5 screens: weight and body condition, oral exam, blood panel, urine test, and blood pressure. Shorten to 6 months if weight moves 10% in a year, if a dental lesion is found, or if the cat is on a long term medication that needs monitoring.
Why switch to every 6 months at age 7?
Because kidney disease and hyperthyroidism become common from that age, and both are silent until roughly two thirds of kidney function is gone. A 12 month gap can miss the stage where a prescription diet or thyroid treatment still protects the kidneys, while a 6 month gap catches the trend in creatinine, urine specific gravity, and weight.
What should I measure at home between visits?
Four things: monthly weight on the same scale, resting respiratory rate counted over 30 seconds at least twice a week, daily water intake at roughly 40 to 60 ml per kg, and body condition scored 1 to 9 by hand. A resting rate above 40 per minute or a steady weight drop is a reason to book early.
