We buy the large dog size of Advantage II and split it into correct dosages for each of our (many) cats
Advantage II for Cats uses the same ingredients found in the canine version. Vets and pet owners generally agree that it's safe and effective. Available without a prescription, it's approved for kittens as young as eight weeks. A single dose, applied to the back of the neck, lasts for one month. Formulations are available for small cats and kittens (under five pounds) to large cats (over nine pounds).
hi jac, unfortunately i cant recommend using the advantage II on cats. In relation to product failure, its never absolute. The kill percentage will gradually trend down as resistance emerges, down from 90+% to 50% or lower. Once its below 70% most owners report it doesnt work at all, unaware how bad the fleas and ticks would be with no product at all. Increasing dose(eg fortnightly), within limits, can boost efficacy, but its a short term victory. Spinosad/Comfortis is now registered for use in cats, but its a big pill and some cat owners have difficulty getting it down. Because its new, its very effective.
Dosage Chart for Adult Cats: Advantage II.
Advantage II for Small Cats 2 pack 2 Doses
Advantage II for Cats gets consistently high ratings from both vets and cat owners. Though it doesn't work for every cat, it's more reliably effective than any other product. One monthly dose, applied to the back of the cat's neck, kills adult fleas as well as eggs and larvae. Yes, the dosage is the same for Advantage and Advantage II. The difference between the products is this: Advantage required adult fleas to ingest the medication, at which point they would be impacted by the insect-specific neurotoxins and die. Advantage II kills fleas on contact, with the addition of three new chemicals to its formula, that makes your dog or cat’s skin an entirely inhospitable environment for pests. Eggs are killed before they hatch. Adult fleas are killed and will fall off, or will be washed off in your dog’s next bath.No muss, slight fuss. Advantage II comes in single-dose tubes. To apply it, you part the fur at the back of the cat's neck and squeeze out the entire contents of the tube onto the skin. It needs to be applied in a spot the cat can't lick, as ingesting it can cause excessive drooling and hyperactivity. Most owners find Advantage II very easy to apply, although some cats may put up a struggle. The product may leave a greasy spot on the back of the neck; some owners say this dries quickly, while others say it stays wet for days and rubs off on the owner's hands. Most owners don't find the smell bothersome.You’re correct. The ingredients are identical in Advantage II for both cats and dogs. And they’re in the same concentrations. The main difference is the amount of product used. Make sure you’re applying the correct dosage, or toxicity problems will likely occur.
