A cat first-aid kit is 6 groups of equipment and consumables totaling about 26 items, and it needs a 180-day check rather than an annual one. The 3 failures that actually bite are dead batteries in 2 devices, sterile packs that were opened and forgotten, and the round-tip scissors that went to the kitchen drawer. Nothing swallowed or applied counts here — the box holds tools, not tablets.
The kit buys you 10 to 15 minutes of useful action and 4 numbers to read to a clinic. It does not replace an examination, and any of the 10 red flags in the last section means drive, not dab.
The 6 groups, and why each one exists
One, measurement (4 items): a digital thermometer reading to 0.1°C with 2 spare button cells, a kitchen scale at 1 g resolution, a stopwatch, and a small notebook. Two, bleeding and bandaging (8 items): 10 gauze squares at 5 by 5 cm, 5 non-stick pads at 5 by 7.5 cm, 2 conforming bandages 5 cm wide, 2 rolls of self-adhesive wrap 5 cm wide, 1 roll of paper tape 2.5 cm, round-tip scissors, splinter tweezers, and 2 syringes of 10 ml with the needles removed. Three, flushing (4 items): 2 bottles of sterile irrigation saline at 250 ml, a 20 ml syringe for flushing, 50 cotton pads, 2 soft cloths. Four, restraint and transport (6 items): a rigid board 60 by 40 cm, 2 towels at 70 by 140 cm, a carrier 50 by 30 by 30 cm, a soft cone in 2 sizes, and 4 pairs of nitrile gloves. Five, light and warmth (3 items): a headlamp with 2 spare AAA cells and a foil blanket 130 by 210 cm. Six, records (5 items): a copy of the vaccine card, the 15-digit microchip number, clinic and 24-hour emergency numbers, a weight log, and one printed photo of the cat from the front and one from the side.
What must never go in the box
No human tablets, syrups, capsules or topical ointments, and no leftover prescription from another pet. Cats handle many common human medicines badly — a single tablet of a routine human painkiller can be toxic to a 4 kg cat — so a kit that mixes them invites a dosing mistake at the worst moment. Anything a vet has dispensed for this cat goes in a separate zip bag, label facing out, with the date it was opened written on the bag in marker, and it is rotated out at the 180-day check. Tools are unambiguous under stress; bottles are not.
The 180-day check: 6 tasks, 40 minutes
Task 1, dates: read the lot and expiry print on both sterile packs and on the saline bottles; anything within 60 days of expiry gets replaced now rather than noted. Task 2, batteries: swap or rotate the cells in the thermometer and the headlamp, because a spare that has sat 30 months is not a spare. Task 3, thermometer: stir it in ice water for 60 seconds; it should read 0°C within 0.2°C. Task 4, counts: 10 gauze, 5 pads, 2 bandages, 2 wrap rolls, 2 syringes, 2 saline bottles. Task 5, adhesion: press a 10 cm strip of tape onto glass and peel it after 1 minute — if it lifts without resistance it has aged out. Task 6, contacts and weight: confirm the clinic number still connects, confirm the 24-hour number answers, and write the current weight, since a stale weight is the most common reason a phone consultation goes wrong.
| Group | Items | Check every | Replace after | Storage |
|---|---|---|---|---|
| Measurement | 4 | 6 months | cells 12 months, thermometer 36 | dry drawer |
| Bleeding and bandage | 8 | 6 months | opened sterile pack 24 hours | sealed bag |
| Flushing | 4 | 6 months | opened saline 7 days | upright, dark |
| Restraint and transport | 6 | 12 months | after 20 washes | folded, top shelf |
| Light and warmth | 3 | 6 months | foil blanket once used | low shelf |
| Records | 5 | 6 months | weight every 30 days | waterproof pouch |
Storage: 2 kits, 15 to 25°C, 1 m off the floor
Keep the main kit in a cupboard at 15 to 25°C and under 60% RH, 1 m off the floor so a flooded kitchen does not reach it. Build a second, 300 g travel kit for the carrier: gauze, 1 conforming bandage, 1 roll of wrap, tape, a foil blanket, 2 pairs of gloves, and a card with 3 phone numbers. Sunlight and heat are the quiet killers — latex and adhesive degrade 20% to 30% in 6 months on a sunny sill, and a car glovebox at 50°C does the same in 2 weeks. Restocking costs little next to the vet bill it prevents, and the item-by-item refill list is on the refill page.
The first 10 minutes: read 4 numbers, not a diagnosis
Rectal temperature 37.8 to 39.2°C is normal for a cat; the thermometer goes in 1 to 2 cm, angled slightly downward, for 60 seconds or until the beep. Heart rate is 160 to 220 beats a minute at rest — count for 15 seconds and multiply by 4. Respiratory rate while asleep is 20 to 30 breaths a minute; count for 30 seconds and double it. Gum colour should be pink, and pressing a fingertip on the gum should refill within 2 seconds. Write all 4 numbers down with the time, then call and read them out; a clinic triages faster on 4 numbers than on a description. For external bleeding, press directly with a gauze square for 5 to 10 minutes without lifting to check, because each peek restarts the clot.
When to skip the kit and drive
Ten red flags: open-mouth breathing at rest, a respiratory rate above 40, gums that are pale, grey or blue, collapse or a cat that will not stand, a seizure lasting more than 2 minutes or 3 seizures in 24 hours, a male cat straining with no urine for 12 hours, bleeding that continues after 5 minutes of firm pressure, an obviously deformed limb, a temperature below 37°C or above 40°C, and any known exposure to a toxin. In those cases the kit is for padding a wound and keeping the cat warm in the car, nothing more. The clinic-side checklist for what to bring and what to say is on the emergency kit check page, and the consumables arithmetic for restocking is in our cost tool.
Restock rhythm that survives a busy year
- Mark 2 dates: the 180-day full check, and a 2-minute glance every 30 days.
- On the glance, check 3 things: 2 device batteries, 1 tape strip, the gauze count.
- Replace consumables in 1 order a year — 10 gauze, 5 pads, 2 bandages, 2 wrap rolls, 2 saline bottles, 4 pairs of gloves — rather than 6 panic buys.
- Rebuild a used kit within 48 hours, because the second event tends to arrive inside 3 months.
Frequently asked
What goes into a cat first-aid kit?
Six groups of equipment, about 26 items: measurement gear such as a 0.1 degree thermometer and a 1 g scale, bleeding control with 10 gauze squares and 2 conforming bandages, flushing supplies with saline and a 20 ml syringe, restraint and transport with a 60 by 40 cm board, a headlamp and foil blanket, and records including the 15-digit microchip number.
How often should a cat first-aid kit be checked?
Every 180 days, not once a year. Rotate batteries in the thermometer and headlamp, read the expiry print on both sterile packs, calibrate the thermometer in ice water for 60 seconds, count the consumables, test tape adhesion on glass, and confirm that the 24-hour emergency number actually answers. Add a 2-minute glance every 30 days.
Should I keep human medicine in the cat first-aid kit?
No. Cats metabolize many common human medicines poorly, and one tablet of an ordinary human painkiller can be toxic to a 4 kg cat. Keep the box to tools and consumables, and store anything a vet dispensed for this cat in a separate labelled bag that is rotated at the 180-day check so nothing expired is used in a hurry.
