Cat Harness Size Chart
Our harnesses fit cats in two sizes: XXS for kittens and cats under 10 lbs, XS for cats over 10 lbs. Chest is what matters most, so measure before you order.
| Size | Chest(in)(cm) | Neck(in)(cm) | Cat weight(lbs)(kg) | Cats |
|---|---|---|---|---|
| XXS | 11–13½" 27–35 cm | 9½–12" 24–31 cm | 2–10 lbs 1–5 kg |
|
| XS | 14–18½" 35–47 cm | 12–14" 30–36 cm | 10–22 lbs 4–10 kg |
|
In between sizes? We recommend sizing up. Measuring your cat is always the most accurate way to choose.
Kittens are still growing — they wear XXS for now.
How to measure
Neck
Wrap a soft tape around the neck where a collar would sit, snug but not tight — you should be able to slip two fingers underneath.
Chest
Measure around the widest part of the chest, just behind the front legs, with your cat standing. Cats are wriggly — a second pair of hands helps.
No tape measure?
Use a piece of string, mark where it meets, then lay it flat against a ruler.
