All our Homeopathic products are specially diluted in distilled water in the best potency for animals.  Our products also contain a trace amount of alcohol (20%) for conservation purposes only. This is mostly evaporated when spraying the product and with the trace amounts your pet would get, it is almost nothing. In some rare cases, a pet may be sensitive to alcohol which may cause some excessive salivation or some shaking of the head. If this occurs please see the next question to proceed with ways to avoid any trace of alcohol when giving the products. NOTE: when dosing small animals like birds, always dilute the product in fresh drinking water and not directly into the mouth.
