Sizing Chart

First time owners of Cat Jackets must allow for the cat to get used to their new harness in the safety of their own home to ensure that they are comfortable with it. They may flop down on their side and not move. This is not uncommon and should not cause concern.

Dependant on the size of your beloved kitty, our cat jackets are fully adjustable, to meet the needs of a growing kitten to a fully grown adult cat.

Measure your collar size by taking a measurement around where you would add a collar. For the chest you can measure under their chest area just behind the front legs.


Adjustable Collar sizes up to 20cm   - (8 inches)

Adjustable Chest sizes up to 30cm   - (12 inches)

 Adult Cat

Adjustable Collar sizes from 20cm to 30cm  - (8 inches to 12 inches)

Adjustable Chest sizes from 30cm to 35.5cm  -  (12 inches to 14 inches)

Anything above these measurements above will need to be sent to us to make your custom size


If you own a large breed of cat and they exceed these measurements please contact me for a quote on a custom sized harness.
