MeOW! Cat claws for your fancy are here, in a nice height of 7/8ths of an inch. These are fairly thin at the base, so they fit fine on the half inch wide cat collars. You can turn them upside down and use them to hold keys, but I don't think you'd want to do that, really. Let the boys know you have claws and know how to use them, if they get out of line. You're the boss, puss. Hisssssssss.

If you are unsure of the quantity of studs that will fit your strap, you may either inquire first, or order more than you think you need. I can refund an overage, but not charge more for extra (unless you make a new order, which is more complicated for both of us).
