Can i use the frontline plus for dogs on cats? is it the same? I have a 3 pack for dogs 23-44 lbs.. how do i determine how much per cat? I notice the little green container vial is the same size as a cat one but contains twice the amount of liquid..
Actually, the dog frontline has 8.8% methoprene and the cat frontline has 11.8% methoprene. The fipronal is the same 9.8% (according to Cats About Town Society)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!)
