This product is somewhat mediocre (I was using Frontline before giving this treatment a shot). Even after treating my home, my animals still have fleas. I’ll be cancelling my membership, however. This last box that came in, I put on all my furbabies. My dog (14 years old) had a deadly reaction to the flea treatment. He lived his whole life healthy, not a single thing wrong with him. After putting this product on him (from what my Vet told me), he had 6 seizures within 24 hours. Ultimately, I had to have my BEST friend of 14 years, Euthanized. No medicine could save him because of how overheated he became during his seizures. His brain & body simply could not handle & survive this trauma. In closing, please do your research before trying any Flea treatment for your furry ones. I, however, shockingly found out the hard way. Instead of a very vivacious & wonderful friend, I now hold a cold, ash filled Urn 😭
