Using Advantage for Dogs on Cats

I have used Dog Advantage on my cats for years. It's the same ingredients just the dosage is different. My vet suggested that I use this method (I have 6 cats) it is more cost effective. To the person who feeds garlic to their dog...look it up, that is TOXIC.

I just got back form my vet with my cat. She is a 10.11 pound Main Coon and she said Advantage can be used on both but the dosage is very important. She gave me a plastic syringe and told me to only use 0.8 (ml?) from it and no more. She also said Frontline is different for dogs and cats so do not use the dog formula on cats.
Advantage - Yes
Frontline - No

I would not do it. It is made for cats and dogs for a reason. There are some places it pays to be thrifty but where health is concerned why take chances. My personal opinion is this; If a person can't afford to feed and take care of pets properly then they should not have them.

I know these are old posts but others as I did may see this post.
You can use canine Advantage on cats, my vet gave me some of it.
You can't use ADVANTIX for dogs, which is by the same company, but has added ingredients which are toxic to cats.
The ingredients for Advantage are exactly the same, just that dogs are usually larger than cats so there is more in a tube. You have to measure it out for cats:

.4 ml for cats 9 lbs and under and .8 ml for cats over 9 lbs.

Just make sure it is Advantage, not others.

Advantage is the same ingredients for cats and dogs: Imidacloprid. As long as you administer the right dosage, there should be no reason canine Advantage should harm your felines.

However, you should never, ever, ever apply canine Advantix, Frontline or Revolution on your feline as they have separate canine-only chemicals in them.

NO! Advantage for canines is toxic to cats. If you have cats in the home with your dogs, and the dogs are the only ones using Advantage, the canine advantage toxic to the cats. And NEVER use Canine Advantage on cats!

If you are a canine-free home, use Feline Advantage for your cats. If you have dogs, use Frontline Plus on your dogs and use Advantage for cats on your cats.

I DON'T USE ANY OF THOSE PRODUCTS AS A FLEA AND TICK PREVENTATIVE....WAY TOO COSTLY FOR ME...FOR YEARS I HAVE USED ...EXCEL 8 IN 1 BREWERS YEAST TABS WITH OMEGA 3 FATTY ACIDS AND GARLIC...I GET THEM THRU THE MAIL FROM "CHERRYBROOK"..THEY HAVE AN ONLINE SITE... THESE TABS ARE ALSO SOLD IN WALMART, BUT IN DOSES FOR SMALL TO MEDIUM DOGS....I GET THE MEGA SIZE TABS FOR MY TWO BIG DOGS AS THE DOSE IS ALOT SMALLER THAT WAY...BECAUSE THE TABLETS ARE MUCH BIGGER...USING THIS PRODUCT MY DOGS HAVE NEVER HAD FLEAS, THEIR COATS ARE SOOOOO SHINY AND THERE'S ALOT LESS SHEDDING!!!...I SWEAR BY THIS STUFF....LOL AND THE PRICE IS JUST RIGHT!! NO VET NEEDED EITHER...THE PICTURE IS OF MY PUG, "TAZOR", HELPING ME IN THE GARDEN LAST SUMMER....LOL

I use the large Revolution for dogs and separate it for my cats under the VETS orders. Please be careful not to use too much!

Please be careful with these potent but supposedly safe medications. For a natural alternative, try diatomaceous earth powder. It's cheap, safe and works great, both externally and internally--and there's no poisons in it!

I do. I get the largest dog Advantage (not Advantix!) and use .4 for 5 lbs. and under, .8 for over 5 lb. cats. I'm a foster/rescue person and that is what we all use.

I do this all the time. My vet gave me a syringe marked with the amount for my cats. I buy the largest dog kind and give the recommended dosage to my dog and cats. I believe for my cats it is .8 ml, I just use the marked vials he gave me. I've been doing this for a few years and with 4 cats it has saved me lots of money. I can't speak for other flea medications and I know that Advantix is bad for cats but with Advantage it works very well.

I wouldn't, There's more in those for dogs than cats. Thats what a vet told me.
