It's not a good idea. I don't know the ingredients of the product in particular, but a lot of products which are suitable for dogs contain ingredients which act as nerve poisons in cats. Get a cat-specific product, otherwise you can end up making your cat very ill. If the product for cats is weaker, it is for a reason; cats are also more sensitive to some products, some simply because they have much less body mass but others because cats lack certain metabolizing enzymes which dogs have.

The product Advantage can be used on both cats and dogs the same, however it's the dosage size you must watch. This product is gauged by weight and is sold in different dosages for that reason. The ingredients are the same for cat and dog. Frontline, is not a product you can use on both animals , if it is specifically for one or the other. Frontline is a stronger product and can kill your cat if you use the one intended for dogs-and should not be used on Persian cats at all. This is clearly stated on the package warnings.

That is also wrong..the cat version is actually stronger! If you read the ingredients, one of the percentages is higher in the cat version, the only difference is the amount, it goes by body weight and of course cats weigh less. I have 4 large dogs ranging from 50 to 70 lbs and 3 cats so I bought the 3 pc package for dogs 89 to 132 lbs and divided it up by each animals body weight applying certain amount of drops accordingly(the total fluid ounces in the 3 pc 89-132 package was the same as the combined fluid ounces of the cat version and my size dog version added together) The pet store tried to tell me they were different chemicals that could kill my cats...when I pointed out that the ingredients were the same and actually higher in the cat version, then they tried to tell me it wasn't the active ingrediants that would kill my cat but the inert ingredients...I should send them a dictionary with the definition of "inert" highlighted.................My cats are fine, the fleas are dying

No you shouldn't if it's Frontline, in fact you should be careful about using the cat one on many cats as some have nerve problems and react with drooling, and possible seizures. We've had it happen to two of our cats. And be careful using the dog one on Collie type dogs as it has been fatal to some. These are potent toxins we are placing on our pets, ones that are just placed on the skin and last for weeks from absorption into their systems. If your cat is absolutely safe on Advantage, not sensitive at all, then you can try to use the dog Advantage on cats. Get the dog sized large vials and with a syringe, suck up .5ml of it and use that on your cats. It is very cost effective. The newer batches of Advantage seem to be a lesser quality, less potent, often not working for very long, so I suspect they have changed the formula because of all the problems reported on pets. We have been able to use it on 3 of our cats with little problem but it sure doesn't work like it used to.

Of course you can, but only for Advantage! Don't be fooled by above responses to the contrary! The active ingredient, as well as it's concentration, in Advantage is the same for both the cat and dog products that Bayer produces. The difference is the dosage. It is vastly cheaper to purchase the large dog product, which will afford you many more doses for a small cat! In fact, you can save up to 80% by doing this! The key is to apply the correct dosage to your cat. To do this, you will need to purchase a metered syringe (not including a needle!) and an airtight, resealable glass vial in which to store unused medication. The large dog dose of advantage is 4 mL, and the 10 lb. cat dosage is 0.8 mL. Thus, simply empty the plastic vial of large dog advantage into the glass vial, take up 0.8mL of the solution into the syringe, and apply it to your cat. The remaining 3.2 mL of advantage can then be stored for subsequent applications by sealing the glass vial tightly, and storing the vial in the fridge (not the freezer which may cause ingredients to separate!). While it may be that the advantage does not need to be refrigerated once opened, it can't hurt. When purchased, the monthly doses of advantage are placed in individual plastic vials to make application of the correct dosage error free. It might also be due to the possible slow decomposition of the active ingredient in advantage upon exposure to oxygen in air. This possible effect would be significantly slowed by storing the unused advantage in the fridge. The glass vial and syringe can found cheaply at discount medical supply stores. Good luck!

And, the last time I bought Advantage for cats, the vials all contained less than a drop of the stuff. I wish I had kept my receipt. The about of imidacloprid in Advantage for cats is the same as for dogs. And INERT means inert, having no effect. The inert ingredients are probably the same oil used in suntan lotions.

however, now that i think about it, some posters have talked about drooling. our cat drooled excessively before, when i was applying it. i had no idea those two things co-related. he's been off it for months since the vials came from EntirelyPets entirely empty, and he does have fleas, but he is not drooling anymore either. so i'm going to try to find something less toxic. the active ingredient in Advantage is a product that comes from nicotine. (see wikipedia for imidacloprid)

advantage has the same percentages of ingredients for cats and dogs. You can check for yourself.

We run a small cat sanctuary, aproximately 60 cats. The cost of dosing them every month for fleas is prohibitive, but we buy the largest dog size of Frontline Plus and each cat gets .5 ml. as measured with a pipette or syringe. The ingredients are the same with a slightly less strong percentage of (S)-methoprene in the dog version (which makes it even safer for cats). Buy it on E-Bay and they will send you everything you need plus instructions at a very good price. I hope this helps.

NO! Cats are descendent from humanoid feline mongrel-beasts, and as such lack the psyshillic nerve endings in their parietal lobe. The ingredients in the dog version are geared to trigger these receptors.

!!! NO !!! http://www.peteducation.com/article.cfm?c=2+1623&aid=591 Once-a-month Topicals: Once-a-month topical insecticides are applied to a small area on your pet's back, are probably the easiest product to use, and generally last the longest. Some kill fleas and ticks, and others just kill fleas, so check the label carefully. Ingredients generally include permethrin, pyrethrin, or fipronil. Examples include Bio Spot, Advantage, K9 Advantix, Frontline Top Spot, Revolution, and Defend. Since many dog products can be very harmful if used on cats, read the label carefully. Remember: Do NOT use products containing permethrins on cats.

My vet says yes. We get the larger quantity tube, but we get about 5 or 6 doses out of it. Just make sure you use the correct dosage (not the whole tube at once). Our vet gave us a syringe with a mark on it showing exactly how much to use. It is much cheaper and they are the same medication.

Caution;; Be very aware of the decimal point ! 5ml is about ten times the dose that a cat can tolerate.. .5-.8 ml is about right. 1 cc on your syringe = 1 ml. so read 1/2 -3/4 cc.

I ALMOST KILLED SIX OF MY WONDERFUL CATS!!!! DO NOT USE DOG ADVANTAGE OR ADVANTIX on CATS!!!!!!!!!! My vet always gave me Frontline Dog to split up between my 6 cats but I didn't know there was a difference. My vet retired and I used Advantage/Advantix instead. THAY ALL ALMOST DIED!!!!!! I am even now afraid to use Frontline. :~(

Nope

YES. As someone previously stated, Advantage is exactly the same formula and strength for both dogs and cats. When using a larger dog Advantage, you have to dump it into a container and draw up the proper cat dosage. It is the same with Frontline, the ingredient is exactly the same at the same strength. With Frontline Plus, there is a tiny bit LESS strength of one of the ingredients in the dog version. Same deal, dump the contanets into a small container and use the correct dose for cats. Anyone who doubts this should learn to read a label. One WARNING - Do NOT use ADVANTIX on cats, it is toxic to them.

can i use frontline plus for dpogs on my cat?

ONLY Bayer Advantage can be safley used on cats. DO NOT use Bayer Advantix or Bayer Advocate They are both very toxic to cats.

NO!!! It is far too strong and could make your cat seriously ill. Use Frontline instead.
