Propylene glycol
Why it matters
Prohibited by FDA in cat food because it causes Heinz body anemia in cats. Still permitted in dog food and soft dog treats, where it carries a moderate penalty instead.
How PawScore treats it
Foods containing Propylene glycol are auto-avoid when we grade the label. We don't publish the exact numeric weights so scores stay honest as the rubric evolves.
