WellyTails all natural cat & dog supplements are produced by using “HUMAN GRADE” ingredients primarily. However if we can only find research proven ingredients that are of “FOOD ANIMAL FEED GRADE”  we will use these scientifically researched and proven ingredients.

WE DO NOT USE any ingredients that are so called “PET FOOD GRADE” as these type of materials are inferior and have no place in any holistic natural pet supplement.

Please see links above for further information on ingredients.
