This is a flea control product made by a company called Farnam. It is cheaper than most of the major brands - it's about half the cost of most other products, but the other good advantage it has is that it is sold in 3 month quantities instead of 6 month quantities like most other flea medicines. Keep in mind that this makes it look cheaper than it is when you're comparing prices - but the upside is that if you are in an area with a shorter flea season you can avoid wasting money buying more than you need (it varies based on temperature, hotter places like the South have fleas nearly the entire year).

It's made to kill fleas, ticks, and mosquitoes. Both kittens and puppies have to be 12 weeks old at least to use it. It uses an insect growth regulator, which are basically chemicals that prevent flea eggs and flea larva from growing into adults. It combines this with regular insecticide to kill the adult fleas, so you catch them at both ends of the life cycle. You apply drops to the back of your pet's neck, and it diffuses through the pet's skin and coat. It is generally waterproof, but if you use shampoo on your pet in a flea bath it's going to wash it out.

One application of it will last about 3 months for fleas, but only about one month for ticks and mosquitoes, so it's generally good to apply it at monthly intervals if you have problems with either of those in your area.

You should be aware that some vets are reluctant to sell this because of one of the key ingredients: Permethrin. Cats have bigger problems with this than dogs do, but it also affects children, so a lot of people don't like to use it on animals that are around kids. A small number of dogs and cats have been reported to have very negative reactions to this chemical with side effects including seizures. Several other flea medicines have Permethrin (Advantix, Hartz, and Exspot), but this one has it in higher concentrations. My take? There's a reason this is cheaper than brands like Frontline or Advantage. Your pet is probably not going to have those side effects if you give it to them - the vast majority don't - but the risk is higher than with the more expensive brands that use newer, safer chemicals. You have to balance the risk with the cost and make your own choice. I would watch your pet closely though, and if you see anything weird after applying it wash the pet thoroughly and take it to a vet.

For Cats:

For cats, it only comes in one dose, because cats are in a pretty narrow weight range. You can get it for Cats online here. It costs about $13 for a 6 month supply. You can also use this on ferrets (if you have a ferret, get the CAT version, and not the dog one).

For Dogs:

For dogs, there are a couple of different doses. It depends on how much your dog weighs. For small dogs up to 15 pounds, you can get it online here. For dogs 15 to 33 pounds go here. For dogs 34-65 pounds go here. Finally, for dogs who weigh 66 pounds or more go here.
