A cat emergency card is 1 index card, 6 fields, and 20 minutes of writing, kept in 2 places: the carrier pocket and the fridge door. It exists for the 30 minutes when you cannot speak clearly, a stranger is holding your cat, and nobody can read your phone because the battery is at 4 percent. Fill it once, photograph it, review it every 6 months.
Why paper still wins over an app
A phone dies in 6 to 10 hours of hard use, networks drop for 12 to 48 hours after a storm or quake, and a vet nurse holding a struggling cat cannot scroll. A laminated card of 10 by 15 cm fits a scrub pocket, survives water, and reads in 5 seconds. Print 2 copies and store the same text as a photo on 2 phones, so the paper carries the content and the phones carry a backup. Update the card first, then the photo: 1 source of truth, 0 conflicting versions.
The 6 fields, in the order a clinic reads them
Field 1 is identity: name, sex, age, and current weight in kg to 1 decimal, because a 0.3 kg error changes what a vet can safely do. Field 2 is medication: drug name, strength in mg, times per day, and the last dose time. Field 3 is allergies and past reactions, including the year and what happened. Field 4 is diagnoses that change treatment, such as CKD, diabetes, heart murmur grade, or a seizure history. Field 5 is contacts: your mobile, a second adult, and the clinic plus 1 emergency hospital with its 24-hour line. Field 6 is consent and logistics: who may authorize treatment up to a stated amount, your carrier location, and whether the cat bites.
What never goes on the card
No doses. Write the drug, the strength and the schedule, and let the vet calculate milligrams per kilogram from the weight on field 1; a hand-written dose on a card is how a 4 kg cat gets an 8 kg dose at 2 a.m. No full home address beyond street and number, since the card travels through hands you do not know. No diagnoses you suspect but have not confirmed, because a guess written in the same font as a fact gets treated as a fact. No microchip number without the registry name next to it, and no insurance policy number without the 24-hour claim line. Mark corrections with 1 line through and the date, never overwrite.
Where the 2 copies live
| Field | What goes in it | Limit | Review |
|---|---|---|---|
| 1 Identity | Name, sex, age, weight to 0.1 kg | 40 characters | 3 months |
| 2 Medication | Drug, strength in mg, times per day, last dose | 60 characters | 1 month |
| 3 Allergies | Substance, year, reaction in 1 line | 50 characters | 6 months |
| 4 Diagnoses | CKD stage, diabetes, murmur grade, seizures | 60 characters | 6 months |
| 5 Contacts | 2 owners, clinic, 24-hour hospital | 4 numbers | 3 months |
| 6 Consent | Who decides, spend cap, bite warning | 40 characters | 12 months |
Copy 1 goes in the carrier pocket, face out, in a 60 micron sleeve. Copy 2 goes on the fridge door at 140 cm, at adult eye level, with a spare pen beside it. A third photo lives on the lock screen of both phones: 1 tap, no unlock, no scrolling. If you keep a go-bag, the card goes in the top flap, not the bottom, because 20 seconds of digging is 20 seconds lost.
Fill it in 20 minutes: the order that works
Start with field 5, the contacts, because it needs no thought and gets the card usable in 4 minutes. Then field 1 with the cat on a scale: a 4.2 kg adult is normal, a 3.4 kg cat of the same frame is a 19 percent loss and belongs in field 4. Then field 2 from the actual box, not from memory, copying the strength exactly as printed. Field 3 takes 5 minutes if you have had a reaction and 10 seconds if you have not; write none known plus the date. Field 4 needs the last discharge summary. Field 6 is 2 sentences and a number.
Review every 6 months, and after 3 events
Put 2 dates a year in the calendar, 6 months apart, and check 4 things: weight within 0.3 kg of the card, medication list matches the boxes in the cupboard, both phone numbers still answer, and the clinic still has a 24-hour line. Update immediately after a new diagnosis, a new drug, or a move. The card is also the handover document in a disaster: if you evacuate and someone else takes the cat for 72 hours, fields 1, 2, 5 and 6 are the whole briefing, and the poison contacts card covers the number to call when something is swallowed. Field 3 also gets 1 line of plants: the houseplant emergency list is the fastest way to answer a clinic that asks which lily.
People first, then the card
The card never justifies a risk. If a building has a crack wider than 5 mm, a door that will not close, or a gas smell, nobody goes back inside for the card, the medication or the cat: people first, and never re-enter a damaged building. Keep the card where you can grab it on the way out, hand a copy to whoever takes the cat, and let the rescue team search. A duplicated card costs 2 minutes at a print shop; a re-entry costs more than that.
5 steps this week
- Weigh the cat and write the number to 1 decimal on a blank 10 by 15 cm card.
- Copy drug name, strength and schedule from the box, and add the last dose time.
- Add 4 numbers: 2 people, the clinic, and a 24-hour hospital.
- Laminate 1 copy for the carrier and tape the second at 140 cm on the fridge.
- Photograph both sides, set the photo as a lock screen, and book 2 review dates 6 months apart.

Frequently asked
What 6 fields belong on a cat emergency card?
Identity with weight to 0.1 kg, medication with strength and schedule, allergies with the year and reaction, diagnoses that change treatment such as CKD stage or murmur grade, 4 contact numbers including a 24-hour hospital, and a consent line naming who may authorize care and up to what amount. Each field should stay under 60 characters so it reads in 5 seconds.
Why should the card not list drug doses?
Because a dose written for yesterday is wrong after a 0.3 kg weight change, and a vet or nurse reading a hand-written number tends to trust it. Write the drug name, the strength in mg and the times per day, and let the clinic calculate milligrams per kilogram from the weight in field 1. Keep the last dose time on the card instead.
How often should the card be updated?
Every 6 months at minimum, with a check on 4 items: weight within 0.3 kg, medication matching the boxes at home, both phone numbers answering, and the clinic still running a 24-hour line. Update the same day after a new diagnosis, a new drug or a move, and keep both copies identical.
