1/2" wide Cat Safety collars are designed with cats in mind. Available with or without a bell. Strong bar-tack stitching, D-ring (for ID tags only) and a custom designed breakaway buckle with a release point of approx. 4.5 lbs. pressure. To open the collar, simply pull apart at the buckle. Adjustable from 8-to-12-inches. Measure your cat's neck around the mid-point, snug against the fur, then add 5% more for the adjusted collar size. Or, measure the current collar.
