Most senior cat appointments fail on logistics, not medicine. The cat arrives fed, the urine is 5 hours old, the weight history lives in a phone that died, and the clinic spends 10 of its 30 minutes reconstructing the story. Eight items, packed the night before, fix that.
The 8-point checklist
- Carrier out 48 hours early, door open, bedding inside, so it stops being a threat.
- A written medication list with doses in mg and the last 3 dose times.
- Food label plus the daily ration weighed in grams for 7 days.
- A 90-day weight trend, even if it is 4 numbers from a kitchen scale.
- A fresh urine sample, collected the same morning, delivered within 2 hours.
- A stool sample in a sealed bag if diarrhea started within 14 days.
- Two 10-second videos: one of the gait, one of any odd behavior.
- Payment method plus insurance policy number, so cost questions do not eat exam time.
Fasting: 6 hours, with 1 clear exception
Six hours without food is enough to clear lipemia for a standard chemistry panel, a T4, and a glucose. Water stays available the whole time; 12 hours without water skews the urine specific gravity and makes the cat harder to handle. A cat under 6 months or under 2.5 kg fasts 4 hours, not 6, because 6 hours in a small body drops glucose too far. The diabetic cat is the exception that matters: do not withhold food and do not skip the insulin dose unless the veterinarian told you to. A diabetic cat fasted for 6 hours while still receiving insulin can drop into hypoglycemia in the carrier. Feed and dose on the normal schedule, and bring the insulin pen, the syringes, the dose log, and 2 pouches of its usual food. If the clinic wants a fasting glucose, they will schedule a 12-hour curve as its own visit.
The 30-minute trip
Under 30 minutes door to door, no sedation is usually needed; cover the carrier with a towel, keep the car at 21 to 24 degrees C, and skip the radio. Over 30 minutes, or for a cat that screams for the whole ride, ask about gabapentin at 10 to 20 mg per kg given 2 hours before departure; it needs a prescription and a trial dose at home first. Never give an over-the-counter sedative, and never leave a cat in a parked car above 26 degrees C. Book a morning slot when traffic adds under 10 minutes, and arrive 10 minutes early so the cat can settle in a quiet corner instead of the waiting room.
Urine: the 2-hour rule again
A sample older than 2 hours is a different test. Bacteria double every 20 to 30 minutes at room temperature, red cells rupture in 2 to 4 hours, and casts dissolve before 6. Collect the first morning void in a non-absorbent tray, chill the tube at 2 to 8 degrees C, and hand it over with the clock time written on the label. If the sample cannot be fresh, say so: a clinic can take a cystocentesis sample in 5 minutes, and a labeled stale sample is worse than none.
What a senior exam should include
Weight and body condition score 1 to 9, blood pressure, a T4, a chemistry panel with SDMA, a complete blood count, a urinalysis with UPC, and a dental look. Blood pressure should be measured before any handling that stresses the cat, with 3 to 5 readings averaged; a systolic above 160 mmHg on repeated visits is the working threshold for hypertension. Ask for the numbers in writing, not just the word normal, because a creatinine that moved from 1.6 to 2.3 mg/dL over 12 months tells a story that the word normal hides.
| Item | Lead time before visit | Typical cost USD | Minutes in clinic |
|---|---|---|---|
| Exam and history | book 5 to 10 days ahead | 60 to 90 | 20 |
| Bloodwork with T4 and SDMA | fast 6 hours | 110 to 220 | 10 |
| Blood pressure | none | 25 to 45 | 10 |
| Urinalysis plus UPC | sample under 2 hours | 45 to 90 | 5 |
| Dental check or radiographs | fast 6 to 12 hours | 120 to 350 | 20 |
Carrier and waiting room tactics
Set the carrier on the floor, not on a chair, and open the top half in the exam room so the cat can be examined in its own bedding. A towel over the carrier cuts visual input; a cat that can see 6 other animals in a waiting room will spend the first 5 minutes of the exam at 180 beats per minute. Ask to wait in the car and be texted, which works at most clinics and removes the waiting room entirely. For a cat with failing vision, keep the carrier facing you and talk before you touch, since a hand arriving without warning reads as an attack; the vision loss guide covers the handling details.
Weigh before you go, not after
Weigh the cat at home on a baby scale, in grams, 3 times over 2 weeks, and bring the numbers. A 4.5 kg cat that reads 4.2 kg has lost 6.7%, which is the point where muscle loss, thyroid disease, and dental pain enter the differential; 2% is within scale noise. Trends beat single readings, and a trend read from the same scale beats one assembled from 3 different clinics. Home weighing basics are in the weight monitoring guide.
Money, asked in advance
The full senior panel above commonly lands between 240 and 445 USD before dental work, and dental extraction adds 300 to 900 USD depending on the number of teeth. Ask for the estimate in writing before consenting, ask which items can wait 3 months, and ask whether the lab runs in-house at 1 hour or sends out at 24 to 48 hours, because that changes what you can decide the same day. The cat cost calculator splits these ranges by region.
Night-before sequence
- 19:00 — set out the carrier, pack the file, photograph the medication list.
- 21:00 — last full meal if the visit is at 09:00; water stays down.
- 06:30 — collect urine if the cat obliges; chill and label it.
- 08:00 — diabetic cats eat and get insulin as usual; everyone else stays fasted.
- 08:30 — depart, towel over the carrier, no food in the car.

Frequently asked
How long should I fast my senior cat before bloodwork?
Six hours without food clears lipemia for a chemistry panel, a T4, and a glucose, while water stays available the whole time. Cats under 6 months or under 2.5 kg fast only 4 hours. The diabetic cat should not be fasted at all: feed and give insulin on the normal schedule unless your veterinarian says otherwise, and bring the pen, syringes, and dose log with you.
Can I skip the urine sample if my cat will not cooperate?
Yes, and you should say so rather than bringing a stale one. A sample over 2 hours old has doubled its bacterial count 4 to 6 times and lost most of its red cells, which makes the result misleading. Clinics can collect urine by cystocentesis in about 5 minutes, so a failed attempt at home costs the cat less than a wrong lab report.
Should I sedate my cat for a 30-minute car ride?
Under 30 minutes door to door, most cats do better with a towel over the carrier, a 21 to 24 degrees C cabin, and no radio than with any drug. For longer trips or a cat that screams throughout, ask about gabapentin at 10 to 20 mg per kg given 2 hours before departure, with a trial dose at home first. Never use an over-the-counter sedative.
