frontline plus for dogs

NO!!!

Please do not give any medication labeled for a dog to a cat.

MANY cats have died this way.

Google it if you don't believe me.

Actually I just googled it and they are the same active ingredient. But the dosages are different. 

I would ask a vet who is a straight shooter.

This is assuming the dose for a cat and dog of equal sizes is the same. Not a safe assumption.

Maybe if you call the cat rescue I posted the link for

they will tell you the appropriate dose. 

They have a phone number to call.

I am simply not qualified to tell you the correct dose and even if I was you shouldn't trust some random stranger on the internet with this one.

The dosing for cat and dog frontline/advantage/etc differs between the species it's meant for. I know this because my vet told me. Sadie (dog) had picked up fleas somewhere and I only had cat frontline at home, I called the vet and asked, she said I could apply it but it wouldn't last nearly as long because of the way the pesticide absorbs in cats is different than in dogs. You will have to speak to a vet about it, I don't know if the rescue can give you advice because of the legal liability. 

You should really contact your vet to check the proper dosage before you try to administer the meds yourself. You have nothing to lose, a call to the vet is free.

You are also thinking you can accurately divide a large pipette into several doses.

Frontline is the only one you can do this with. But I do it all the time. Its the dosage you have to get advise on. I use a suringe to messure is out.

I do animal rescue and have researched this thoroughly. The ingredients of Frontline Plus are EXACTLY the same for dogs and cats. The dosage is .05 ml per lb. So, a 10-lb cat would get .5 ml. I purchase the Extra-Large dog size, which is 4.0 ml per tube. So, for 10-lb cats, that's 8 doses per tube! I empty a 4.0 ml tube into a small glass vial and measure out each dose using a 1-ml syringe (without the needle, of course). Then I use the syringe to apply each dose to the back of the cat's neck, just as you would with a tube. The cost difference is amazing, because the price for each tube is basically the same, whether 4.0 ml for an extra-large dog or .05 ml for a 9-lb cat! So, for example, if the cost for one .5 ml tube (a cat-size dose) is $10, the cost for one 4.0 ml tube (extra-large dog-size dose) is also $10. THEREFORE, instead of paying $10 per cat-size dose, I pay only $1.25 per dose. Other animal rescuers and I have been doing this for years, so SPREAD THE WORD! (Caveat: You can do the same thing with some generic brands of Frontline Plus, but not all! Just be sure you check the ingredients of the generic brand to make sure they are exactly the same as Frontline Plus, which is fipronil and S-methoprene. Some of the generic brands replace the S-methoprene with different ingredients for cats and dogs. For those brands, you CANNOT use the extra-large dog formula on cats!)
