Contains an insecticide. Complete with silver bell. How to UseDo not remove the collar from the blister until ready for use. Fasten around your cats neck (coloured side facing outwards) , leaving enough room to insert 2 fingers between the collar and neck. Do not fit too tightly, to ensure against irritation, but do not fit too loosely, or the cat may be able to get a foot or tooth under the collar, in an attempt to remove it, and become caught up. Remember to periodically check and loosen the collar if fitted onto a growing cat. Cut off any collar sticking out beyond the buckle. Wrap this cut-off in a bag and throw it in your dustbin. Keep the empty blister card for reference until the collar is thrown away.
