Cat Protector Knuckle Keychain White. The eyes of the cat become finger holes and the ears become spikes when clutched in the hand to create an excellent means of self-defense against an attacker. The white finished stainless steel charm includes a stainless steel ring and clasp for attaching keys. This keychain looks non-threatening, is easy to carry, and will provide you with peace of mind!
