Yes, I learned the hard way that saving $5 isn't that big a deal. Last year, we had a truly horrific flea season. We were really hurting financially and we decided to try Hartz It wasn't until after I put it on Allen that I heard about its side effects... and I prayed that nothing happened to him (it didn't, but I still worried.)

Anyway, that cheap stuff didn't manage to kill one flea. And smelled TERRRIBLE for weeks afterwards... like really rancid baby powder. I combed them every day... and combing did help a lot. We waited until 4 weeks passed before I could reapply another form of flea prevention. I was smart and went to the vet that time.

I need to make a vet appointment to get this year's supply... I'd rather not get infested this year.
