I have three cats and I'm not sure what flea medicine I should get them. They stay inside but they also go outside a lot during the day. There's a field behind my house and they go in it a lot and catch mice and just play in it. Since they're in the field and outside I think I need one that also protects them from ticks. I've heard that K9 Advantix is good for fleas but it doesn't protect against ticks. I know that Frontline protects against fleas and ticks but I've heard that it doesn't work anymore because the fleas are immune to it.
