Fitting
Size Guide
Measure your cat while they're standing. Use a soft tape measure and keep it snug but not tight. When in doubt, size up — our tops are designed with a relaxed fit.
How to measure
- Back Length — from the base of the neck to the base of the tail.
- Chest Girth — around the widest part of the chest, just behind the front legs.
| Size | Weight (est.) | Chest Girth | Back Length |
|---|---|---|---|
| S | up to 2 kg | 30 cm / 11.81" | 20 cm / 7.87" |
| M | 2 – 3 kg | 35 cm / 13.78" | 25 cm / 9.84" |
| L | 3 – 4 kg | 40 cm / 15.75" | 30 cm / 11.81" |
| XL | 4 – 5 kg | 45 cm / 17.72" | 35 cm / 13.78" |
| XXL | 5+ kg | 50 cm / 19.69" | 40 cm / 15.75" |
All measurements are of your cat's body, not the garment. If your cat falls between sizes, we recommend choosing the larger size.
Weight column is an estimate only. Cat body proportions vary significantly between breeds — weight alone is not a reliable indicator of size. Always measure your cat before ordering. Mewse accepts no liability for incorrect sizing based on weight estimates.
