I went to my vet today and see if they would sell me some, he was not in but his assistant was very helpful. She said they no longer sell interceptor because they have moved to the new products that prevent heartworm and fleas. In addition to the milbemycin oximet that is in interceptor this product (Trifexis) contains spinosad to kill the fleas. Can I use this product?? Just went to novrtis website and they no longer manufacture Interceptor and have closed the factory.
