This year we asked our vet about Advantix. She said they do not carry it for 3 reasons.

1. Often people think if they are repelling mosquitoes they do not need to use heartworm medication. This is not true, you still do.

2. It can not be used a home with cats.

3. It does not repell all kinds of mosquitoes and more speciaifaclly does not repell those that carry West Nile. I don't really know about this reason...my mom's vet said she didn't know there were diffrent kinds of mosquitoes.

Our vet said she didn't not think advantix was a bad product, they just felt rather then having to explain this things to everyone it was safer continueing with Frontline Plus, which is what we use.
