Best tick treatment?

[fluttershyby]

Currently using advocate and treated her only last week. Since then found two dead ticks and today a very much alive one which I've removed.
Looks like it's not working very well, can anyone recommend an effective one before I ring the vets to get a different one?
Thanks

Advocate doesn't treat ticks. I think stronghold plus does

Frontline for ticks

Don't think frontline is as effective against fleas at the moment though

When I first got the cat the vet recommended advocate I need something that does both as I guess I can't use two different brands at the same time?

Advocate covers fleas and some worms but not ticks. Stronghold plus covers fleas, some worms and ticks. Speak to the vet as there might be another product they recommend for ticks

The products that cover for ticks are:

Stronghold Plus ( not the regular one)
Bravecto
Frontline
Broadline

Thanks, I'll give them a call today.
