I use front-line on my dogs and cats and it works really great. I have tried many brands and no other brand has worked for me. I do use an Adams flea and tick spray on the areas that my pets sleep and it seems to work pretty well. I remember way back when that companies use too warn about possible reactions to certain treatments and how your pet could have bad reactions. (kinda like how deet affects some children ) As with any drug there are always some who will be allergic to or simply there body can't handle certain chemicals. My mom has a cat that is highly allergic to fleas and has lost most of her hair a couple times during flea breakouts. We use to have a dog that was allergic to fleas and he had to go in for allergy shots when fleas got too bad him.

I used a flea prevention product by Hartz once that made my cat lose his hair at the place where I applied it. I mentioned it to the vet who told me that Hartz is not safe and has in some cases caused seizures. Whether or not that is documented I don't know, but that is what the vet told me. I do know for a fact though from my experience that Hartz can make the animals lose hair.

I currently use Frontline and haven't had any problems but I will double check with my vet now that you said that. I used Advantage for many years in the past and never had any problems.

My cat reacts to Frondline plus badly. Hair lost on neck, redness and swelling + exercise drooling.( buy org. stuff from Vet. not counter fit ) . He is O.K. on Advantage - no problem, no fleas. Frontline does not work on my dogs (6)

either - no reaction, but a lot of fleas. Dogs get now K9 Advantix - not problem , no fleas.
