Can stronghold flea treatment harm your cat if it is out of date by 2 months?

Using an out-of-date Stronghold flea treatment on your cat may not be effective and could potentially pose some risks. While it might not be immediately harmful, the efficacy of the medication can diminish over time, leading to insufficient flea control and possible side effects. It's always best to consult your veterinarian before using any expired medication to ensure the safety and well-being of your pet.
