We have human grade tapioca in our Squeezables for two reasons. Firstly, tapioca helps to give PureBites Plus Squeezables the creamy texture that dogs and cats love.  Secondly, tapioca is a highly digestible source of carbohydrates and energy for dogs and cats. Tapioca is not considered a potential allergen and is often used in diets for pets that have food sensitivities.
