The lens shows a reading task
The lens opens four prepared explanations of label categories discussed by FDA. Species is not the same as weight class, and a product’s intended setting is not the same as the animal it can be used on. Choosing a card does not scan or verify a package. There is no image upload, product database, barcode lookup or hidden compatibility model. The tool is a reading aid only.
A mismatch is not solved with arithmetic
FDA says dog products must not be used on cats and that the product must match the pet’s species, life stage and weight class. This website will not divide a dog dose for a cat, combine products, infer a minimum age or choose an application amount. Those would be clinical or label-specific decisions outside this tool. If wording is unclear, ask the veterinarian or manufacturer rather than inventing an interpretation.
Read the current package, not a memory
FDA notes that directions or warnings may change, even for a familiar product. It advises keeping packaging if a problem needs to be reported. Our examples are not a substitute label and do not claim to track current formulations or approvals. Keep the exact product and its instructions available for the professional conversation. Actual reactions need direct help, not another lens setting.
