Petsmart

wal-mart or petsmart or petco….

Nwhere the junk they sell over the counter is all garbage, go to your vet and get Frontline or Advantage

check out a good pet store, they should have what you are looking for.

Go to Petco.

Try a good pet store.

Maybe Petco or Cat R Us.

How about going to the vet?

garlic works awesome! (put a little in their food) Fleas dont like the taste it gives their blood. A lady that used to baby sit me growing up had a poodle that was severely allergic to fleas. that worked the best without the side effects of OTC.
FYI.. otherwise your local pet store or Petsmart

you can get it pretty much anywhere such as petco petsmart and any vet.

advantage and frountline work great i youse them on my cats and dog

i have heard horror stories about cheap products, though more expensive I'd go with frontline or something from your vet. if your cat has an allergy to fleas than you might like the idea of garlic most cats don't mind the taste and in my experience it repels fleas very well. just mince it up and mix into your cats food.

the worse thing to do to your cat is to give that over the counter junk! It's a well known fact that the stuff doesn't work.
More importantly it has been known to create many health problems including death.
Call up your local vets office and ask how much a single dose of advantage cost's, It should run about 9 bucks, not a bad investment for your kitties health.

You can get them at petland,petco, petsmart,walmart,meijer. However you should be very careful when using these. I would really suggest especially if your cat has allergies to fleas that you take it to the vet and let them recommend a medication. Often when cats have allergies these over the counter meds can cause reactions such as rash hair loss and itching. I know because it happened to one of my cats
