A Ragdoll grows for three years, gains weight faster than almost any other breed, and hides a heart condition behind a temperament so calm that owners read "relaxed" when the cat is actually slowing down. The year is mostly about the scale, the comb, and one ultrasound.
Weight: slow curve, monthly check
Females finish at 4.5-6.5 kg and males at 6.5-9 kg, with the frame still filling out at 30-36 months. Weigh monthly from the start and never stop: this is the breed where an extra 500 g a year goes unnoticed until the cat is 2 kg over.
- 3 months: 1.5-2.2 kg
- 6 months: 2.8-4.0 kg
- 12 months: 4.0-5.8 kg
- 24 months: 5.0-7.5 kg
- 36 months: 4.5-6.5 kg female, 6.5-9 kg male
One kilogram over the top of the band is a genuine health risk in this breed, not a cosmetic issue, because the extra load lands on joints that were never built for it. A monthly gain above 200 g after the cat is 2 years old means the portions are wrong, not that the cat is still growing.
The year at a glance
| Period | Coat and hairballs | Weight and health |
|---|---|---|
| January-February | Comb twice a week, 5-10 minutes | Monthly weigh-in; the winter kilo is the hard one |
| March-May | Daily combing during the shed; expect more hairballs | Book the annual heart check; raise the wet food share |
| June-August | Twice a week; bath every 8-12 weeks if the coat feels dry | Watch drinking; keep the room under 26 C |
| September-October | Twice a week; second hairball peak of the year | Weigh-in; dental check if breath has changed |
| November-December | Twice a week; nails every 3-4 weeks | Year-end weight, vaccine dates, parasite dose |
Coat and the hairball calendar
The coat is silky with very little undercoat, so a comb twice a week for 5-10 minutes covers it and daily sessions from March to May handle the shed. Bathing every 8-12 weeks at most, with a light conditioner, stops the coat drying out; more often than that strips it.
Hairballs cluster in March to May and again in September to October. One every two weeks in those windows is normal for a cat that grooms this much; more than two a month outside them is a reason to look at water intake and grooming rather than to buy paste. A cat that retches without producing anything, or vomits after every meal, needs a vet, not a supplement.
HCM: the screening schedule
Hypertrophic cardiomyopathy in this breed is tied to a well-documented MYBPC3 R820W variant, and good catteries combine DNA testing with an annual echo. Your own schedule: a first echocardiogram at 12 months, then one every 12 months, and every 6 months once a murmur or a thickened wall is found. Ask for both parents' echo reports before you buy.
Count sleeping breaths once a month: under 30 a minute is normal, 30-35 is worth a recheck, and a persistent 40 plus, especially with hind-leg weakness or open-mouth breathing, is an emergency. Ragdolls are so placid that laboured breathing can look like a deep nap.
Kidneys, stones, and water
PKD is inherited through PKD1 and cleared with one DNA test; without one, ultrasound at 12 months and again at 3 years looks for cysts. Calcium oxalate stones are the other kidney-adjacent risk, driven by low water intake and dry-only feeding, so aim for 45-60 ml of water per kg a day and keep at least half the diet wet.
From age 7, add a blood panel and blood pressure to the annual visit. A Ragdoll that starts drinking from the tap or the shower floor is telling you something about the kidneys long before any blood test does.
FIP and the stress budget
Ragdolls are over-represented in feline infectious peritonitis cases, and while the reason is not settled, stress and multi-cat density are the factors an owner can actually change. Keep the household to a number of cats the space supports, add a second litter box per cat, and avoid rehoming churn: a stable routine is cheaper than any supplement sold for immunity.
Watch for a fever that comes back after antibiotics, weight loss with a good appetite, or a belly that looks full while the spine stays thin. Those three together mean a same-week appointment.
Feeding and exercise for a cat that would rather lie down
Keep kitten food until 12-15 months because growth is slow, then switch to measured adult meals: a 6 kg adult needs roughly 260-300 kcal a day, and a 7.5 kg one about 300-340. Half or more as wet food covers both the obesity risk and the urinary risk in one move. Treats at 10 percent of calories, which is 30 kcal.
Two wand sessions of 8-10 minutes a day, dragged low along the floor, plus a food puzzle for one meal. Ragdolls do not climb for fun, so a stable tree at 1 m gets used and a tall wobbly one does not. A ramp to the sofa is worth more to this breed than a tower.
Mistakes that cost the most
- Judging weight by eye, when the coat hides 1-2 kg.
- Free-feeding a breed that gains 500 g a year without trying.
- Skipping the 12-month echo because the cat "is calm, that's just how Ragdolls are".
- Treating hairballs with paste instead of water and grooming.
- Letting a Ragdoll outdoors, where its reaction time is a liability.
When to call the vet
Breathing over 40 a minute at rest, open-mouth breathing, a fever that returns after treatment, a distended belly with a thin spine, straining in the litter box with no urine, or a sudden reluctance to move. The first two cannot wait for a convenient appointment.
The four habits that carry the year: weigh monthly, comb twice a week and daily from March to May, book the echo every 12 months, and keep the diet at half wet food with portions measured.
Frequently asked
How many hairballs are normal for a Ragdoll?
One every two weeks during the March to May and September to October shed windows is normal for a cat that grooms as much as this breed does. Outside those windows, more than two a month points at dehydration or an uncombed coat rather than at a need for paste. A cat that retches and produces nothing, or vomits food repeatedly, needs an examination instead of a supplement.
At what age should a Ragdoll have its first heart scan?
Twelve months, then annually for life. The breed carries a documented MYBPC3 R820W variant, and the DNA test alone does not rule out disease because other mutations exist. Ask for echo reports on both parents before buying, and from age five keep counting sleeping breaths monthly, since a rate above 40 a minute at rest is the earliest sign most owners can catch at home.
Why does my Ragdoll keep gaining weight on the same food?
Because its energy use falls faster than its appetite. A 6 kg adult needs about 260-300 kcal a day, and most owners are feeding 350 or more without measuring. Weigh the portion on a kitchen scale, split it into two meals, keep at least half as wet food, and reweigh the cat monthly; a gain above 200 g a month after age two means the portion is still too large.
