I recently purchased Hartz First Defense for flea control since I have 5 cats and was looking for something a little more affordable that Advantage.
Is this product really harmful to my cats? I have been reading some on line information and it’s really scaring me to go back to Advantage. Could you give me an educated opinion on this product.
Our Vet Says:
Hartz First Defence has the same active ingredient as Frontline Top Spot. My personal opinion is to use Advantage or Advantage II. If you have a problem only with fleas it is better to use Advantage but if you have a problem with fleas and ticks you need to use product that has the active ingredient Fipronil.

Congratulations to the winner of this month's Question
of the Month,
who wins $100 for the following question:
I just purchased Frontline Plus for my 3 little girls - all long haired Chihuahuas. I haven’t seen any fleas on them but they are scratching like crazy. I’m wondering about applying this product to them and our sleeping arrangements. They all sleep with us and most of the night it’s under the covers. Is this something I should be worried about once I’ve applied this medicine to them?
