Treating My Dogs for Sarcoptic Mange Can I also Treat My cats?

Hi There Again,
Here I have yet another question…
I have been treating my dogs for Sarcoptic Mange after my Maltese began loosing his fur…Long story short he was being treated for allergies bu my vet since october, I got a second opinion from another vet after I realized my other dogs were scratching, they found scabei (mites) in the skin scrape now I am treating all my dogs.
The meds and dip have been working great and my dogs look so much healthier and happier especially my old boy who lost most of his fur beacuse of all this. I herd it can pass to my rabbits and cats…:( My rabbits have no contact with my dogs so Im not that worried about them, but my cats walk about the yard, they dont come in direct contact but I just want to know if I could use the same dip which is called DEMADEX (I have put it on the link below) and its to treat Sarcoptic and Demratric Mange plus some other things in dogs. Can I dilute it in a spray bottle and spray it on my cats? I have two and Turkish Angora who loves pleaying with water and my Siamese who hates it! So my question is can I use the dogs formula which is the DEMADEX Rinse put it in a spray bottle and spray it on my cats? Revolution doesn’t control Mange on cats just dogs. I am using Advocate which the vet recommended as it also controls mange.
Please let my know if I cant what else can I do? Can I make a home mix myself??
What about Malaban? Could I use that? Its simular to Demadex although Demadex is more thorough.
Thanks Everyone I would greatly appreciate anything :)
I cannot wait till the day all this is over…I have owned dogs all my life and have never had anything like this before :(

If it helps my dogs are all under the 5kg mark so I dilute 5mls of Demadex to 1 liter of water according to my vet.

Thanks again!!!

I have a cat that had sarcoptic mange…more common in dogs, but my cat also has a non specific immune disorder. My cat was treated with I think Ivermetrix, which is indicated for dogs. He recovered, but was under vet supervision, as dog medicine is usually not indicated for cats. Cats are very sensitive to all kinds of chemicals, meds, etc. My point being, no home remedies for cats.
