This product is a self defense cat keychain. If you ever worry about you or your kids, friends, or families safety then this the keychain for you. I decided to create this self defense keychain because my parents have always been cautious about my safety especially at fairs. The ears on this keychain are sharp enough to scare and pierce a bit through an intruder. The eye sockets are holes to put two of your fingers through so you have a nice grip on the keychain. The way the keychain looks makes it seem like it is only used as an accessory so no one will expect it to protect you. All YOU need to do is by any type of ring and connect the mouth of the cat keychain to your keys, bookbag, ect. I hope you enjoy this product. Thank You!
