Cat harness size chart and measuring guide

Choosing the right size is essential for safely using a cat harness. An ill-fitting harness can lead to unexpected accidents, such as your cat slipping out and escaping. Always measure your cat carefully to ensure you select the appropriate harness size.

Key Points

  • Measure your cat while they are standing on all four paws.
  • Choose the harness size based primarily on the chest girth.
  • Size is adjustable with a wide 2.0" (5 cm) hook-and-loop closure.

How to Measure Your Cat's Exact Size

How to measure the exact size

The "exact size" refers to the snug measurement of your cat's body without any slack.
When your beloved cat is relaxed, measure them while they are standing on all four paws. You will need to measure three areas: the base of the neck, the chest (girth), and the belly.

*Note: If your cat is a bit wiggly or you don't have a soft measuring tape, you can use a piece of non-stretch string or yarn, and then measure the string with a ruler.

Measuring the Base of the Neck

Measure slightly lower (towards the shoulders) than where a collar normally sits. Gently part the fur to ensure the tape fits snugly against the skin at the base of the neck.

Measuring the Chest (Girth)

Measure right behind your cat's front legs (the armpits). This is the most critical measurement when choosing a harness size. We recommend measuring 2-3 times to ensure accuracy.

Measuring the Belly

Measure the belly about 1.6"–2.0" (4-5 cm) further back from the armpits towards the tail. Make sure your cat is standing on all four paws while measuring.

How to Choose the Right Harness Size

Choose a size that matches their exact measurements or is about 0.4" (1 cm) larger. For safe usage, the most important factor is ensuring the chest girth fits perfectly, even more so than the base of the neck or belly measurements.
