ADJUSTABLE SIZE: Neck circumference: 5.1–8.6 inches, suitable for cats under 4.4 lbs. Features an adjustable drawstring to customize the fit and ensure comfort. This collar is also suitable for small dogs and puppies such as Chihuahuas, French Bulldogs, and Pugs. Please measure your pet's neck to select the correct size. USE WITH UPPER BODY WOUNDS: This soft recovery collar helps prevent your cat from licking or scratching wounds on the upper body, promoting safe healing. It is not recommended for use with spay/neuter recovery or injuries on the lower body, as pets may still reach those areas. Confirm the wound location before use. COMFORTABLE & LIGHTWEIGHT: Made from soft and lightweight PP cotton material, this collar is gentle on your pet's neck and skin. Compared to traditional plastic cones, it offers a more comfortable fit and does not interfere with eating, drinking, playing, or sleeping. ADORABLE & PRACTICAL: Designed in a donut shape, this collar is both stylish and functional. Its soft, pillow-like structure can double as a supportive cushion during naps. For best results, secure the adjustment strap after fitting to prevent removal. EASY TO USE & CLEAN: No inflation required. Simply adjust the drawstring and fasten. The collar is machine washable or hand washable for easy cleaning. After washing, reshape as needed. If you experience any sizing issues, please contact the seller for assistance.
