Save it to your pantry and the pantry page flags it if it turns up in an FDA recall we import.
It adds up, line by line.
Every product starts at 96. Flags, the brand's transparency grade and any recall linked to this product take points away. Nothing else moves the number, and no brand can pay to move it.

Plus for Cats
Good, check the flags
Scored October 2026 · checkthepanel.com
2 flagged ingredients.
Avoid first. Each flag costs points in the score above; where a flag has an entry behind it, it links to the evidence.
Pesticide actives
Printed as actives: fipronil 9.8% and (S)-methoprene 11.8%. Labelled for cats.
Undisclosed material
The label totals everything besides the actives as one share without naming it, so there is nothing to look up; the flag is about the missing names, not a known hazard.
Every ingredient, top to bottom.
Listed as printed on the package. Tap any line to see what it is and why it's there.

The brand behind it.
Frontline
Spot-on flea and tick treatments, made by Boehringer Ingelheim Animal Health. Graded from the 2 products of theirs in this catalogue, not from an audit of the company.
Not enough to grade: we hold 2 panels of theirs, read from the carton photos on its product pages, which print no ingredient statement in text. Each names the actives with their percentages and gives the rest as one unnamed share. The C grade takes 5 points off this product's score.

Third-party lab findings for things that never appear on an ingredient label. This is separate from the score above and does not change it.
We haven't found published third-party lab results (PFAS, heavy metals, phthalates) for this product. That is not a clean bill of health, just an absence of data.
