In between sizes? We recommend sizing up. Measuring your pet is always the most accurate way to choose.
Cat collars are one-size fits most.
How to measure
Neck
Wrap a soft tape around the neck where the collar sits, snug but not tight — you should be able to slip two fingers underneath.
No tape measure?
Use a piece of string, mark where it meets, then lay it flat against a ruler.
