Comfortable L-size harness made of breathable mesh material. - Color: Red - Size: L, Neck 40cm, Chest 38-50cm 5 to 7 kg - Model Name: PET Harness I bought this thinking it would fit my 8kg cat, and although the website mentioned both dogs and cats, it seems to be designed for dogs. It has a wide design to prevent strain on the neck during walks. Thank you for looking.
