Sophie was at the "spa" (a/k/a groomer) yesterday, and of course the conversation always ends up discussing the upcoming flea & tick season. She mentioned Bayer's flea & tick collar, Seresto, and that all her clients who use it on their dogs really like it. The groomer specializes in small dogs.

I have never heard of Seresto, and use K9Advantix II on Sophie. I found some internet forums where a few cats had problems, and a few amazon.com reviews said their dogs had problems, but that can happen with any flea and tick preventive.

Have any of you used Seresto, or know anyone who uses or has used it? Opinions or comments? They are quite pricey because they last a long time, so that makes me think twice before jumping in.
