where can i buy revolution for cats

[Seaside]

it seems that at my vet they only sell Advantage over the counter but I want to switch over to Revolution.
Does anyone know where I can find it over the counter?

Don't know, but just thought I'd mention that my cat brought a whole, horrible flea infestation to us (thanks, cat). Treated her with Advantage, fleas were gone in only a couple of weeks. Don't know why you want to switch, but if you're worried about effectiveness, from experience, Advantage works.
