Cat Elizabeth Collar Size Chart and Measuring Guide
Choosing the right size for an Elizabethan collar is crucial. To ensure your cat's comfort, always measure their neck circumference and select a collar that fits perfectly.
Key Points
- Measure the neck circumference with a tape measure or string.
- Allow enough room for 1-2 fingers to fit comfortably.
How to Measure the Neck

Measure your cat's neck circumference at the narrowest part of the neck. The trick is to part their fur and fit the tape measure snugly. This measurement will be their "neck size."
*If your cat becomes agitated or you don't have a tape measure, you can use cotton string or a non-stretchable cord, then measure the length of the string afterward with a ruler.
How to Choose the Size of a Cat Elizabethan Collar
When fitting an Elizabethan collar, allow enough room for 1-2 of your fingers to fit comfortably. A size that is neck size + 2-4 cm is ideal, so refer to the size chart to make your selection.
●Example 1
Neck size 18cm + 2cm allowance = 20cm neck circumference
Select Elizabeth collar size M
●Example 2
Neck size 25cm + 2cm allowance = 27cm neck circumference
Select Elizabeth collar size LL

Poponeko's Elizabethan collars are adjustable to three sizes with Velcro fasteners. Fine adjustments can also be made, so there's no problem of it being too loose and falling off or too tight and uncomfortable. A "Velcro fastener guard" is included to protect the skin from any excess Velcro after adjustment. Even long-haired cats can use it with peace of mind.
