I have a 1 yr old male cat, and 10 week old kitten. The kitten has fleas really bad..I have her in the bathroom. Before I even noticed that the kitten had fleas, she had some contact with my cat. I didn’t see any fleas on him, but should I buy the advantage flea killer just in case?? If he doesn’t have fleas can I still put it on him as a preventative?Or is it just for cats that have fleas? I am going to the vet today to buy Advantage.

What gets rid of fleas and the cycle the best? I have 2 persian long haired cats.
@itsme: I have shaved them before so I am well aware of the hilariousness

I’ve been using Advantage for the last year or so and it has always worked wonderfully, but it hasn’t been working all that well lately and it seems the fleas returned just after a few days. I am thinking that maybe I should switch treatments, but I’ve heard that Frontline doesn’t work as well as Advantage and I’d hate to spend money on something that doesn’t work. What other alternatives are out there that actually work?
