Agreed with the Hertz. Also don't use Sentry Guard. I tried it because it was cheaper, and does not work. Didn't hurt my cats, but I don't think it works well. It might have helped as there is less flea's on my cats, but it does not kill them or repels them like it says it does.
I went out and bought Advantage II today. Cost a lot, but I believe this stuff will work as it has high review marks. I also was able to get a 3 month supply, being I only have two cats and it comes with 6 applications.
I have used the bowl treatment with great success. I use a night light and each night less and less flea's. I also vacuum like crazy and wash my bedding and my cats bedding every other day. I believe this problem will be over soon, I am hopping for a really hot day to kill a lot of the outside flea's. I hear they can't survive well in heat as high as 91 degrees.
As for the person with Kittens, I thought that Advantage and Front Line makes ones for kittens that are over 8 weeks old? I know what you mean about being careful. I have a pet bird and that really limits my options
