ArchieComic Fan I haven't had any luck with anything over the counter but I went back to Advantage from my vets because of what happened to my friends cats. On New Years Eve a few years ago her cats had fleas so she bought Zodiac which is over the counter stuff. Her cats started to foam at the mouth and we rushed them to the vets. She had to put her cats down and the vet told us that there have been numerous complaints about Zodiac as well as Hartz killing pets. So now, I stick to the vets. Here it costs $10. a tube for Advantage or Revolution but I can buy it knowing that it works and it is safe on my pets plus my dogs are chihuahua's so on one tube I can do all the dogs if I get the tube used on big dogs and divide as per the vets instructions. She also told me it is safe on cats to.
I have used shampoos in the past and they worked somewhat but it was alot of work bathing them once a week and not good for their skin.
