Neck Guard Size Chart and Measuring Instructions
To ensure your cat is comfortable in a neck guard, choosing the right size is crucial. Since cats vary greatly in body shape and size, always measure your cat's size before selecting a neck guard.
Key Points
- Measure while your cat is standing on all four paws.
- Use a tape measure or string to measure the neck circumference.
- The ideal size is the nude measurement plus approximately 2-3 cm for ease of wear.
How to Measure Nude Size

Nude size refers to the exact body measurement without any allowance for ease. While your beloved cat is calm, measure the narrowest part of their neck with a tape measure. Part the fur and measure snugly around the neck.
This measurement is your cat's nude neck size.
*If your cat becomes agitated or you don't have a tape measure, you can use cotton thread or a non-stretch string as a substitute, then measure the string's length with a ruler later.
How to Measure Neck Circumference
Measure the narrowest part of your cat's neck with a tape measure. This is where a collar would sit. Part the fur and measure snugly around the neck.
How to Choose a Neck Guard Size
Since the nude size is a snug fit, when choosing a neck guard size, allow for a little extra room. An allowance of approximately 2-3 cm will ensure it's not too tight and easy to put on.
●Example of Size Selection
Neck nude size 20cm + 2cm allowance = 22cm
Select M size with a finished neck circumference of 22cm.
