Just curious about what you use. Since Zoe is going to be an indoor cat and sleeping with me, we really do want to prevent fleas and ticks. So we want a high-quality brand of prevention. We are looking at the two top brands: Frontline Plus and Advantage. I've been reading reviews and it seems that more vets and customers reccomend Frontline more highly than Advantage though I'm sure both are superb. But they're really expensive... I'm shopping around on the Internet, including on 1800PETMEDS.COM for the cheapest prices. There are also 3 or 4 places in town where we can look as well, and we will on Wednesday when we go into town. I think there's a Vet Pharmaseutical (sp?) place in town where we've gotten medicine for cattle and horses before, and it's less expensive, so I will check there definitely. But what do you use and does it work well? Why do you use that specific brand?
