Size Guide

Measure your cat’s neck with a measuring tape for the best fit. If you don’t have one handy, use the breed guide below. If you’re between sizes, go with the larger option.

• Kitten — fits necks up to 7.1" (8.9" cord length) — For kittens or small breeds with slim necks, such as Siamese, Burmese, Abyssinian, or Devon Rex.
• Standard — fits necks up to 8.3" (10.1" cord length) — For most adult cats of average size, typically over a year old.
• Large — fits necks up to 9.4" (11.3" cord length) — For larger breeds such as Maine Coon, Ragdoll, British Shorthair, or Savannah.
