They do that when they lick some of it. Be sure to place the ointment
exactly in the middle of the head. It's easier if you have someone who can
hold the cat for you.

I have not heard bad reports about Advantage.   However, Revolution, which
is a similarly applied product does kill hair follicles in about one out of
50 cats.  Hair will come out in the particular area where product is
applied, and it will not grow back.  Ever.

I prefer Revolution, however, and I've only had one cat out of my large
brood who was affected by spot hair loss because of its use.

I imagine that some cats' skin could be sensitive to Advantage and or
Revolution and might make them uncomfortable.

Kelly, one of my cats is old and is at risk healthwise. We just don't take
chances with him, since he's previously had a bad reaction to Frontline
(drooling, panting, running, rolling and all the hair fell out from his neck).
He had a reaction so bad to vaccines three years ago he almost died. Anyway, we
don't vaccinate him or treat him for fleas anymore. Long story but here's the
point I was making.
The other three cats are treated with Advantage, and the yard is treated around
the house. Over the past three years, Yoda hasn't had fleas. It's almost as if
by treating the lawn and the other cats, he is protected too. You could try it
with your kitties. (I have *no* basis or reference for this information, it's
simply anecdotal. But it wouldn't hurt to try)
