I know enough not to spray anything directly on a cat that is not from a medically-researched product line. We should all keep in mind the ridiculous attempt by Sergeants to make a more "natural" flea treatment that ended up killing some animals and making many very, very sick. Lots of natural things are toxic, like arsenic, for example. Any adult should know that just because something is made from "natural" ingredients doesn't make it safe for you or your pet to ingest or inhale.
I bought Wondercide at Home Depot thinking I could use it to be sure some non-washable things in my home, like area rugs and throw pillows, were flea-free after a little scare we'd had with a cat visitor.
Now they don't claim their product is all-natural, but they state that it is "non-harsh", which makes you think they mean it is made from natural ingredients.
Well, number one, it is harsh as Hell, if you go by the smell alone. (I am not inclined to taste it, but think about how your cat or dog is always licking his or her fur...!)
Despite what one reviewer said about a Wondercide product she had used, that there was fine print on her bottle stating "not for use on cats", my bottle says it IS for use on and around cats. The bottle I bought of "Wondercide Flea and Tick Pets and Home" lemongrass-scented spray that claims it "Kills, Repels and Prevents Fleas, Ticks and Mosquitos" DOES say it is meant to be used ON dogs and cats. Also, there is a line, "pH balanced for dogs and cats", from which anyone would infer that the product was definitely safe to use on and around their cats.There are several other references to using Wondercide directly on your dog or cat.
DON'T DO IT. My 8 cats would not go near anything sprayed with Wondercide ever again. The smell is so overpowering that even after washing a small, fluffy area rug that they used to love sleeping on, they will no longer go near it. One little cat girl coughed for 5 minutes after sniffing the first thing I sprayed, a pillow-bed for cats. It's trash now. You CANNOT remove the scent of Wondercide.
I am not surprised at all that so many people on various sites had medical emergencies from Wondercide being topically applied or being inhaled by their dog or cat.
For Heaven's sake, people, it's OK to use a chemical product to repel and kill parasites. Many times in life the benefits of preventing an infestation or any kind of ill health outweigh the risks involved in using a chemical product. Like chemo-therapy to kill cancer. It nearly kills you as well. You weigh the risks and benefits.
I have used a chemical-filled product, Flea 5X (from PetMeds), for over 10 years on my usual group of 7 to 9 house cats. They remain ridiculously healthy. And flea-free. You apply it behind their neck monthly. The product works great and per my vet has everything needed to kill fleas and flea eggs, plus stop a couple of other parasites' life-cycles, like ticks. Lots of other excellent chemical products like Revolution, Bravecto, etc. have years of research proving them safe and effective for cats. Why spray some "non-harsh" Wondercide perfume, basically, with no animal trials showing it truly kills fleas AND truly is safe.
PLUS, note that the instructions on Wondercide mention over and over to use as often as needed, even daily! It says it is for "daily use and as needed"! The flea treatments sold by Chewy and vets and PetMeds and other businesses are used monthly or, for some pretty expensive ones, every 2 or 3 months. Flea 5X is $9 per does and always lasts a full month or longer. When the prices go down even more, my husband buys a years' worth at $7 per dose!
So that's my brief advice. Stay away from Wondercide.
