It is best to get someone to help you when measuring your cat.
Please measure your cat's Girth , Neck and Under Belly.
(Clearly state either "cm" or "in")
Please send both neck measurement through.
This measurement is just behind the inner front leg to the inner back leg, while they are in the standing position.
Measure just behind the two front inner legs around your cats tummy, see diagram blue line (this is the approximate FINISHED SIZE that the jacket will come to you in, this needs to be a close snug fit, but also a comfortable fit, see image example above with Autumn wearing the jigsaw print walking jacket.
TIP: Take two girth measurements, one standing and one in the sitting position, as in either position your cats girth may be bigger.
