Kitten Home Exam: 6 Checks in 3 Minutes a Week

A kitten can lose 10 percent of its body weight in 48 hours and still meet you at the door. That is why a 3-minute home exam beats a yearly checkup: 6 checks, once a week, always in the same order. You are not diagnosing anything. You are keeping a baseline, so that on the day a number moves you catch it on day 1 instead of day 4.

Why weekly, and why only 3 minutes

Between 2 and 16 weeks a healthy kitten gains 10 to 15 g a day. One weigh-in says almost nothing; 6 weekly weigh-ins draw a curve, and the curve is what catches a fading kitten before it stops eating. Three minutes is roughly how long a 6-week-old tolerates handling before it starts to wrestle. Run the same 6 steps in the same order, write each number down with a date, and stop while the kitten is still relaxed. Nursery staff who hand-raise litters work at about 30 seconds per step, which is where the 3 minutes comes from. If you are still in the first days, the hour-by-hour schedule in the first 72 hours at home matters more than this routine; start the weekly exam once the kitten is eating on its own.

1. Weight, on a scale that reads 1 g

Use a digital kitchen scale with 1 g resolution, not a bathroom scale. Weigh once a day at the same time, before the first meal, in a towel-lined bowl, and subtract the towel. A newborn of 90 to 110 g should gain 7 to 14 g a day and double birth weight by day 10 to 14. At 4 weeks expect 350 to 450 g, at 8 weeks 700 to 900 g, at 12 weeks 1.1 to 1.4 kg. A kitten under 12 weeks that holds the same weight for 2 days in a row is a phone call; 3 days is an appointment. Weigh daily for the first 2 weeks, then twice a week, then weekly after 12 weeks.

2. Temperature, taken rectally

Use a digital thermometer with a flexible tip, lubricated, inserted 1 to 2 cm, held for the 10 to 60 seconds the model needs. Normal rectal temperature at 4 to 12 weeks is 38.0 to 39.2 °C (100.4 to 102.6 °F). Below 37.5 °C is hypothermia and a reason to call before you do anything else, because a cold kitten cannot digest. Above 39.5 °C is fever. Skip ear thermometers under 8 weeks: the canal is too small to aim at the tympanic membrane and readings run 0.5 to 1.5 °C off. Take it once a week, and any time the kitten feels cool to the touch behind the front legs.

3. Gum color and capillary refill

Lift the lip and look at the gum above the upper canine. Salmon pink is normal; pale, brick red, or yellow is not. Press the gum with a fingertip for 2 seconds, release, and count until color returns: under 1.5 seconds is normal, 2 seconds is borderline, over 2 seconds means shock or dehydration and a same-day visit. Yellow gums suggest jaundice, blue-grey suggests poor oxygenation. Check the gum and not the tongue, because holding a 10-week-old's mouth open is how hands get bitten.

4. Skin turgor at the scruff

Pinch the skin between the shoulder blades, lift about 1 cm, release, and count. It should flatten in under 1 second. A tent that stands 2 to 3 seconds suggests 5 to 8 percent dehydration; more than 3 seconds suggests over 8 percent, which in a 600 g kitten is roughly 50 mL of fluid missing. Turgor lies in chubby kittens and in kittens under 3 weeks, whose skin is loose by design, so read it next to gum color and how much the litter box is producing. A kitten urinating less than 2 times a day needs fluids, not a wait-and-see.

5. Sleeping breath rate

Count chest movements for a full 30 seconds and multiply by 2. The 15-second count times 4 is faster but less accurate, because kittens breathe irregularly. Sleeping rate is 20 to 40 breaths a minute. Over 60 while asleep, any open-mouth breathing, or 2 or more episodes of coughing in an hour are emergencies at any age. Watch from 1 m away. A kitten that notices you will slow down and wreck the count, which is exactly why this check is best done 10 minutes after it falls asleep.

6. Eyes, ears, and the rear end

Eyes clear, no green or yellow discharge, no squinting in daylight. Ears pale pink inside, no black coffee-ground debris, no head tilt. The rear end clean and dry: matted fur under the tail means diarrhea, and a red or swollen anus in a kitten under 8 weeks needs a vet rather than a wipe. This step takes 20 seconds and finds more problems than the other 5 together, partly because diarrhea is the leading reason a 5-week-old crashes within 24 hours.

The 6 numbers and their red lines

Check	Normal, 4-12 weeks	Call today if
Weight gain	10-15 g per day	0 g for 2 days
Rectal temp	38.0-39.2 °C	under 37.5 °C or over 39.5 °C
Capillary refill	under 1.5 seconds	over 2 seconds
Skin turgor	under 1 second	over 2 seconds
Sleeping breaths	20-40 per minute	over 60 per minute
Urine output	3-5 times per day	under 2 times per day

Print this table and tape it inside a kitchen cupboard. A number on a wall gets checked; a number in an app gets forgotten by week 3. Write the date next to each entry, because a weight of 780 g means one thing at 8 weeks and something else at 10 weeks.

What to do with 8 weeks of numbers

Photograph the page every Sunday. If you ever need an emergency clinic at 2 a.m., the trend is the most useful thing you can hand over.
Take the log to vaccinations at 8, 12, and 16 weeks; vets read a curve faster than they read a description.
Weigh the food, not the bowl. A kitten eating 20 percent less for 2 days shows up in grams before it shows in behavior.
One kitten alone eats less than a pair; if you are raising a single, read single kitten syndrome before you blame the food.
If the numbers are fine but the shape looks odd, a breed size estimate is a different question entirely, and the breed quiz is the place to start.

The rule that keeps this useful: normal numbers with a kitten that acts wrong is still a vet call. A 38.6 °C kitten that will not stand is sicker than a 39.4 °C kitten that is eating.

Frequently asked

How often should I weigh a kitten at home?

Daily for the first 2 weeks after arrival, then twice a week until 12 weeks, then once a week. Use a 1 g kitchen scale at the same time each morning before the first meal. A kitten under 12 weeks that gains 0 g for 2 days in a row needs a vet call, because weight is the earliest measurable sign of illness in kittens.

Can I use a human ear thermometer on a kitten?

No, not under 8 weeks. The ear canal is too narrow to aim at the tympanic membrane, and readings run 0.5 to 1.5 °C off in either direction. Use a flexible-tip digital thermometer rectally, inserted 1 to 2 cm, and expect 38.0 to 39.2 °C as normal for a kitten between 4 and 12 weeks old.

What if all 6 numbers are normal but the kitten seems sick?

Treat behavior as the seventh number and call the vet. A kitten with a 38.6 °C temperature that will not stand or will not eat is sicker than one at 39.4 °C that is eating well. Bring your written log to the visit; a 6-week trend tells the vet more than a single exam can.
