You can use an Elizabethan collar for an hour or so after the
application. They are commonly available at pet supply stores.

Occasionally. The dose may have been too large. I prefer to give the
minimum effective dose, which for Advantage is a little less than
.05 ml/lb of body weight. The large tube is .8 ml which will treat a
cat close to 20 lb. You might want to cut the dose in half next
time. For kittens I put a drop on my finger and rub it into their
necks.

On the other hand you might want to return the rest of the
Advantage, presuming you bought a six-month supply, and try
something like Revolution, Frontline or Program.

No, you want to stick with a simple, effective and regular once a
month treatment. The flea bites the cat and dies or, in the case of
Program, does not lay viable eggs. A bath today wouldn't help
tomorrow when your cat picked up more fleas outside.

I prefer Revolution, particularly for an outside animal. It is a
little more expensive but also controls heartworms, ear mites and
other parasites. Again I'm careful to give only a minimum dose to
each animal. I have had no problems with it and I handle rescues
many of whom come in covered with fleas.

You should have called your vet rather than or at least in addition to
asking us in this case.  The standard procedure when a cat or dog shows
sensitivity to Advantage is to bath it.  I'd still call your vet as soon as
you can.  I understand reactions are fairly uncommon but they do happen.
My beloved cat Zipper lost his hearing in 1993 after a flea treatment and
the final conclusion was that he was the 1 in 500,000 cats that ever had a
reaction to it.

Call your vet.  It's what they are there for.  Your cat just may not be able
to handle it.  Get professional advice before doing anything more.

-------
A flea dip was a standard form of flea treatment back in the days before
products like Advantage and Frontline were invented. The veterinarian would
essentially give the cat a bath in insecticide. It killed the fleas that
were currently on the cat but did nothing to prevent fleas or kill any fleas
that might hop onto the cat once the bath was over. I suspect that many cats
got sick from this treatment. Back in the early 1990s, my cats had flea dips
on two separate occasions. It was very nasty, and despite the dips (and
having flea-bombed our apartment in the cats' absence), the cats were again
covered with live fleas as soon as we brought them back to our apartment.
