Sizing Measurement
Measure the narrowest part of the neck, fitting snugly.
Allow extra length (fitting in one or two human fingers in between) based on the neck circumference and select the appropriate size.

5.12 - 6.30 in | Approx. 6.30 - 7.48 in | XS |
5.91 - 7.09 in | Approx. 7.09 - 8.27 in | S |
6.69 - 7.87 in | Approx. 7.87 - 9.06 in | M |

Notes:
- As each Catlog Belt is handmade by craftsmen, the overall length may vary by up to ±10mm.
- "Collar length" is the length of the entire collar, including the sensor (Catlog Pendant + Catlog Belt).
- If the collar is too loose, your cat may easily get choked and the measured data may be inaccurate.
