That new one that is by advantage but also covers mosquitos. I know you can use the large size advantage but don't know about the advantix. I want to try the advantix since I'm in Florida and the mosquitos are horrible right now.

Please don't use the Advantix on a cat. Some vets are even saying that people with cats AND dogs in the house shouldn't use it on the dog. The active ingredient in Advantix is highly toxic to cats.

Thank you for letting me know! I couldn't find anything about it on the internet. I already have a tube coming for the dogs but after what you said I think I'll give that one to my brother for his dog and just get the regular advantage for here.
