I treated Moo with Advantage Multi for kittens last night (serious case of fleas and flea-transmitted worms) Moo was a little itchy where it was applied but nothing serious. It might have been worse if the vet hadn't dosed her with an antihistamine to treat the itching from the fleas. It's hard to determine 100% cause & effect with Moo based on Moo's current health. My boyfriend's cat was dosed with an adult Advantage Multi since she's in the same house with Moo - she had no reaction beyond annoyance at the wet spot between her shoulder blades. (We live separately right now - additionally Moo continues to be under quarantine for another few days, until the Drontal has had time to clear Moo's system of tape worms )
Revolution has a different active ingredient than Advantage Multi - So unless it's an allergy to something mixed with the treatments, she should be ok with the Advantage Multi?
Revolution's active ingredient is selamectin
Advantage Multi is imidacloprid + moxidectin
Frontline & Frontline Plus treat only fleas and ticks, not parasites they may carry, or at least there's no comment regarding parasites in the product info. Advantage Multi kills fleas (no comment regarding ticks) and treats ear mites, round worms and hook worms, prevents heart worms. Revolution kills fleas (no comment regarding ticks), prevents heart worms, treats ear mites, round worms and hook worms.
Just based on my research, please correct me if I'm wrong.
And I think I figured out why my vet always sends me home with dewormer for my cat based on this info. Since she has never had a flea problem, has never tested positive for any type of worm infestation, and is strictly indoors, I don't treat her with any of these products. I'll probably treat my cat with a dose of the adult advantage multi now that I've researched a little bit and am more informed on feline heart worm disease. I'm generally very much against unnecessary medical treatment in both humans and animals, but maybe it's time to get them all on a regular schedule of something like this, living in Mosquito Capital USA (south florida).
