Bio Resonance Frequency Pet Tags. Just like humans our cats and dogs have subtle energy systems such as chakras and meridians. Our pets get stressed and just like people these subtle energy systems become unbalanced and blocked. Petifi Technology Balances Subtle Energy Systems. Petifi uses the same delivery technology as our human Frequency Wristbands to deliver natural resonance frequencies every 15 minutes. The frequency protocols have been developed in consultation with a fully qualified (MRCVS) Veterinary Surgeon who has established an international reputation for treating animals using a wide range of cutting edge medical technologies.
