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 bought advantage 2 for my dogs. I have 4 and three of them weigh about the same. The smaller one weighs about 25 lbs. I need to know why the advantage is not working on them and also if you could recommend a flea and tick medicine that will work. They stay inside more than out. My girls are itching up a storm and I feel bad for them. Please help us. BTW Sable was a few months younger in the picture.
