This is a very normal experience when feeding our PureBites Plus Squeezables. The first thing to remember when feeding any PureBites treat, food or topper is that we use high-quality ingredients you can read and trust in all of our products. Our Squeezables have only 5 high-quality ingredients in every pouch and no artificial preservatives or colors to maintain a consistent look. Pet parents can expect some natural color variation at the top of the pouch as oxygen comes into contact with our creamy treats / toppers. Rest assured that dogs and cats will love the taste and pet parents love the superior functional nutrition of PureBites Plus Squeezables.
