I have two dogs and I have yet to have any issues with fleas. I use Frontline by Top Spot. I apply it once a month.
I have my dogs out in heavily wooded areas about 3-4 times a day and they have not yet had fleas or have I ever found any ticks on them. I have actually found 2 ticks on me this year once I got home from walking them. I suggest checking out "petscriptions.com" as I found them to have the Frontline the cheapest. I didn't think it would work but after finding ticks on myself and not the dogs, I will keep using it. Sorry, but I have no experience with kitties. Good luck with your pets.
