Book holiday boarding 4 weeks out, finish vaccinations at least 14 days before drop-off, hand over 6 items in writing, and watch the camera twice a day. Those 4 numbers are the difference between a cat that comes home thin and shut down and one that comes home within 100 grams of where it started. Holiday weeks fill 3 to 4 weeks ahead in most cities, so the booking date is the first deadline, not the last.
Why the booking window is 4 weeks
Four weeks covers three things that cannot be compressed. Boarding kennels and cat hotels run 70 to 90 percent full over the last 2 weeks of December and the 7 days around Lunar New Year. A vet appointment for a health certificate and vaccine review needs 3 to 10 days of lead time. And a cat that has never boarded needs 7 to 10 days of crate practice before the trip. Book at 28 days, confirm in writing at 14 days, and ask for the room size and the daily routine in the same message.
Vaccines 14 days before, not 14 minutes
Rabies and FVRCP vaccines need roughly 14 days to produce a protective response, and most boarding contracts require proof dated 14 days or more before arrival. A vaccine given the day before drop-off satisfies the paperwork and not the immune system, which matters in a building with 20 to 40 cats. Ask for the exact dates on the certificate, check that the FeLV status is documented for cats under 1 year, and keep a photo of the certificate on your phone. If the cat is overdue by more than 3 months, restart the series early enough to finish 14 days before travel.
The 6 handover items
Write them down, because verbal handovers lose 2 of 6 by the second shift. Item 1: food, brand, and grams per day, in pre-portioned bags. Item 2: medication, name, and the exact clock times. Item 3: litter type, since a switch mid-stay causes 2 to 3 days of refusal. Item 4: vaccine booklet and any chronic condition with the last 3 lab dates. Item 5: your number, a backup number, and a spending limit for vet care. Item 6: behavior notes, such as hides for the first 48 hours or refuses food when watched. A single sheet, printed twice, signed at drop-off.
What the room should measure
| Checkpoint | Target number | Why it matters | Ask to see it |
|---|---|---|---|
| Room temperature | 20 to 24 degrees C | below 16 the cat stops eating | thermometer photo |
| Relative humidity | 40 to 60 percent | above 70 percent, mold and stuffy air | hygrometer on wall |
| Floor area per cat | 1.5 square meters minimum | under 1 square meter, urine marking | tape measure |
| Cleaning frequency | 2 times a day | 1 time a day means a wet box by night | cleaning log |
| Noise at head height | under 60 decibels | dog kennels next door run 70 to 85 | phone meter, 1 minute |
| Staff checks | every 4 hours | a cat that stops eating is caught in 8 hours | shift sheet |
Two camera checks a day, 5 minutes each
Ask for camera access or a scheduled video call, and watch at 08:00 and 20:00, which is when most cats eat. In 5 minutes you can check 4 things: food disappearing, water level, litter box use, and resting breathing rate, which sits at 30 to 40 breaths a minute in a calm cat and over 40 means call the staff. Look at posture too, a cat flattened in the corner at both checks is not settling. Keep a short log; 2 checks a day for 7 days is 14 data points, enough to spot a trend before it becomes a crisis.
Red lines that mean call the vet, not the sitter
No food for 48 hours is the hard stop, and 72 hours in an overweight cat risks hepatic lipidosis, which is far more dangerous than the stress that caused it. No water for 24 hours, vomiting more than 3 times in 24 hours, labored breathing at rest, a cat that cannot stand, or no urine for 24 hours all move to a vet call the same day. Give the boarding staff written permission to authorize 1 exam and a spending cap in advance; a 2 hour delay in reaching you can cost a day of treatment.
The 72 hours before drop-off
Feed the same food at the same hours for the last 3 days, and send 7 days of that food plus 3 extra portions in case you are delayed. Put the crate in the living room 10 days before travel with the door open and a worn T-shirt inside. On the day, no big meal in the 2 hours before the car, keep the car at 20 to 24 degrees C, and cover the crate on 3 sides. Trips over 2 hours need a 15 minute stop to check breathing and temperature; the car travel guide covers the heat math, and the holiday food hazards piece covers what relatives should not feed the cat.
Coming home, weigh on day 1
Weigh the cat within 2 hours of getting home and again on day 3. A loss of 100 to 200 grams over a week of boarding is common and recovers in 5 to 7 days; a loss over 300 grams, or no regain by day 5, needs a vet visit. Expect 24 to 72 hours of hiding, reduced appetite, and clingy behavior. Keep the house quiet, skip visitors for 3 days, and do not bathe the cat on arrival. If a new plant or a gift basket came home with you, screen it in the toxicity lookup before it reaches the floor.
Five steps for the next trip
- Book at 28 days, ask for room size and cleaning log, and confirm in writing at day 14.
- Check vaccine dates now; the last dose must land 14 or more days before arrival.
- Print the 6 item handover sheet twice and sign it at drop-off.
- Set 2 daily camera reminders at 08:00 and 20:00 with a 5 minute check each.
- Leave a written vet authorization with a spending cap and a backup phone number.

Frequently asked
How far ahead should I book holiday boarding?
Twenty-eight days, and confirm in writing at 14 days. Holiday weeks run 70 to 90 percent full in most cities, and the last places go to people who called first rather than to the best facility. Booking at 28 days also leaves room for a health certificate appointment and 7 to 10 days of crate practice for a cat that has never boarded.
Can the vaccine be given the day before boarding?
It satisfies the paperwork and not the cat. Rabies and FVRCP need about 14 days to build a protective response, and most contracts require a certificate dated 14 days or more before arrival. In a building with 20 to 40 cats, that window is the point. Check the certificate dates now and move the appointment earlier if the math does not work.
What if my cat stops eating at the boarding place?
Forty-eight hours without food is the hard line, and 72 hours in an overweight cat risks hepatic lipidosis. Ask staff to log grams eaten at every meal, and to call you at the 24 hour mark rather than at 48. Leave written permission for 1 vet exam and a spending cap so treatment does not wait for a phone call.
