I am not sure if there are any natural remedies for fleas, you will lilkely need to purchase a spray for you cats and possible something for the house if they are bad. I purchased many years ago "Hartz" flea spray, it kills the eggs and fleas on the cat. Now my cat hated it, but with one application they were gone, and she had them pretty bad. Also keep in mind that fleas can cause tape worms in your cats, so the sooner you can get them undercontrol the better. Make sure you check your cats bottom for little sesame seeds that may be around their bottoms or anywhere they lay. If you find these then your cats has tape worm and will need to go to the vet. When I took my cat 13 years ago, it was 1 pill that cost $10 and it took care of the tape worm.
Good luck

COLLARS AND PROFESSIONAL SPRAYS CAN KILL YOUR CAT AS QUICK AS THEY KILL FLEAS.

2 years ago I spent almost one thousand dollars, total, on all kind of remedies which didn't work, then finally....

SALT---50 cents a pound regular kitchen salt; LOTS of it; spread it on every carpet in your place.

BUT, COVER THE SALTED CARPETS WITH PLASTIC TARPS, CUT FLUSH TO EDGE OF WALL----CAUSE THE SALT CAN SICKEN YOUR CATS.

spend next few weeks waiting for fleas to die, while every day combing fleas out your cats and simply throwing the fleas into water to die; simple drowning will kill captured fleas.

the salt is like glass to fleas----cuts right through their shell. once fleas are gone, vacum up salt real good.

i still have salt in corners of my carpets, behind radiators, and in closed closets----fleas love the dark.

Another thing I always did was to take a small flea collar that was one of those white plastic ones and chop it up and put it in the vacuum cleaner bag and then vacuum the whole place really well. It helps to kill the fleas and eggs that get sucked up off the carpets and floors. Then secure the top of the vacuum bag and get it to the outdoor trash immediately.

You'll need to wash the cats' bedding and the areas where they like to sleep. They will especially harbor fleas. You'll also need to bathe the cats to help make their skin feel better. Their are oatmeal based shampoos that are designed to help skin. Good luck.

yes, flea collars in vacume cleaner bag....and 4ever checking chairs and bedding.

you're supposed to vacume carpets regularly----but at same time the heat from vacume also makes the eggs hatch quicker! can't win.

turn up the air conditioning too to fight fleas, though might have to worry about cats getting sick from cold.

best to confine cats to easily cleaned rooms till fleas are gone.

I have an Electrolux canister good vacuum cleaner will suck the oxygen out of the air if I let it ,,,, someone told me that putting moth balls in the bag is a good way to kill fleas in the vacuum without changing the bag every time I vacuum...these bags can get expensive over time,, or crush mothballs into powder and spread around with animals out of the room for a while ???

I have taken it to the next level of bombing the rooms ..see if that does the trick,, Cats jump about and stay off of the floor as much as possible lately ,,,who can blame them,, also using garlic in their diet ,,,

stating the obvious . ,,,, vacuum up the mothball powder before letting animals back in ,,

even a hint of mothballs can ruin your cat's kidneys---NO MORE MOTHBALLS.

cats like high places, no matter what; all cats like high spots to check for predators---it's in their genes.

just keeping your cats inside will help; they'll just keep on getting fleas----and feline leukemia----from being outside.

GARLIC CAN KILL A CAT-----NEVER GIVE GARLIC TO A CAT.

Mycroftt: It's best that before you actually do things, to research them on the internet first. The damage you can do to a pet will cost you far more in vet bills, then the time it takes to look it up on the internet or to call your vet.

Also, there are natural flea collars and you may want to investigate some of them and discuss them with your vet.

Also, if you have fleas in your home, it is a lot less expensive to keep using new vacuum cleaner bags than for you to get fleas in your couch and in your bedding and you eventually heading to the doctor and needing to take both cats for a vet visit.

Research about fleas and what they can carry. It's worth it to jump in there and work hard to get rid of them.

Also, do NOT BOMB THE HOME when pets are anywhere in the home. You have to be gone for so long. When you return you have to wipe counters thoroughly and vacuum because it is a pesticide that you just used and exploded all over and it's not good for you either.

yes, asTimeGoesBy...research!

i read so much stuff about cats and fleas 2 years ago, including all kind of conflicting stuff.

a dollar flea comb, and combing the fleas off of cat is certainly yucky, but that really has to be done to get rid of fleas.

nightmarish and mind boggling how can comb all the fleas off a cat in morning, kill them, and then find more fleas on cat at night to do same with.

I use Advantage on the cats and it ususally works in one try if not then not more than 2. If the problem is in the house, I use a premise spray I get from the vet called Vetkem - Siphotrol Plus 2. It treats 2000 square feet. Once the spray is dry, you can let your cats back in the place it was sprayed. We used to use it in the basement and we had NO bugs of any kind for a very long time. That spray kills fleas, eggs and larva. All stages which does a great job. Hope you can get this and it works for you too.

I read about garlic and cats,, ,so ,, no more garlic ..they didn't eat it anyway except perhaps once ,,,they are ok,,, but no more ,,though they have a yeast/garlic powder as a supplement ,, so there is a contradiction here ,,, the ASPCA says no garlic so that is good enough for me ,,,

the mothballs are in the bag in the vacuum. not on the floor or rug,,, so there is no contact ,,.. Also got a generic Lufenuron 165mg for once per month,, I sprayed the outside today and around the perimeter by the doors windows etc.

Bombing is with the cats in another residence totally for most of a day,, and I intend to vac and mop before they come back....I know to be cautious, but the fleas gotta go.. the cats are 24/7 indoor,,

I always use Raid Flea Kill. it is in a purple and black can. costs about $7. it works well and doesn't smell so bad. i have 6 cats who go in and out. i spray it on every fabric surface, including sofas, beds, carpet, curtains....everything. good luck.

The life cycle of a flea is about 3 months, so you will need to retreat the home, yard before then and keep doing it until the Fall. Also, watch the cats for pale pink gums which mean the fleas have sucked too much blood and them have anemia and go to the vets.

I forgot to mention that because they have fleas, they should be getting tapeworm treatment because that's what ingesting the fleas will give them.
