A cat collar should fit comfortably, but make sure you can fit two fingers between collar and neck. Check carefully under the collar on a regular basis for redness or hair loss caused by an ill-fitting or unsuitable collar. Warning: When using liquid flea treatments on your cat, please remove their collar as the chemical may react with the material and buckle. Some animals don’t appreciate being put in accessories. If your pet becomes agitated in any way, please don't force them to wear accessories. Ensure this product is suitable for your pet. These products are not indestructible so for your pet's safety, examine the item regularly for wear and tear and replace at first signs of damage or if parts become detached. WARNING: CHOKING HAZARD Pets can chew items unexpectedly - Seek immediate veterinary attention if any material is ingested. Not suitable for kittens. Not suitable for children. Responsible pet ownership supports pet health & wellbeing - and that's important! Please keep this packaging for future reference.
