Pet Remedy works with the pet’s own natural calming mechanisms by mimicking GABA (gamma amino butyric acid) which is a natural calming agent present in all mammals, reptiles, and birds. So when a pet becomes stressed or anxious the Pet Remedy actives fire up nerve cells into thinking they are getting a message from the brain to calm. This is why it starts to help instantly.
