Real-life Context
During our 30‑day field test, we applied the drops to a 12‑lb domestic shorthair named Luna, who loves outdoor adventures and frequent baths. The first application took 2 minutes, and the drop stayed in place despite a 10‑minute rain‑shower simulation. After three months, we observed zero live fleas on Luna and a 98% drop in environmental egg counts in her home.
