Used this for my cat after a spay and it worked brilliantly as a cone alternative. He moved around naturally, ate normally, and slept in his usual positions none of which were possible with the E-collar. The elastic, breathable fabric kept the wound covered consistently without any slipping. The size guide is accurate; measuring back length as the primary reference gave a perfect fit. Machine washable is a genuinely useful feature when managing a post-surgery pet. I’ve since used it again for a skin allergy flare-up to stop him scratching versatile and well worth keeping in the pet first aid kit.
