Seresto

I've only recently heard about this product and yesterday saw it on sale at Petsmart.  I use Frontline for my cats and I'm not sure if they would be happy wearing a collar (they never have since I've adopted them), but the 8 month duration does sound good.

Any experiences you can share?  Thanks.

I would be very wary of using ANY flea collar. The active ingredient in them is supposedly the same one that is in Advantage (both are made by Bayer Co.), but I have had bad experiences with collars.

I would suggest that you read all the reviews, both from the UK and US, before getting them for your cats. As they are quite pricey, be sure before you purchase.
