I just got a supply of Nemex -2 for deworming my cats. Anyone out there have a dosage "rule of thumb" for this med in cats? Bottle only gives dog dosages...?

Your best bet is to ask a vet. I used to use this, we called it Strongid then on horses. I'm wondering why you bought this?

If it only has dog dosages on it you purchased the wrong wormer.
Cats use a different wormer than dogs, do not give this to your cats.

It might be given because of the cat's age, but it only kills hookworms and round worms, I believe.
Where are you Windy?

Hi, I saw incorrect info on here regarding this so went to an ask an expert site for the following:

There are many treatments available through your vet, which are safe. Revolution is a topical medication that should be applied monthly (though it is a little expensive). Strongid and Nemex are two brands of pyrantel pamoate, the medication I prefer due to its safety and low cost and use with my own cats. Your vet can provide this for you, or you can get it online or at pet stores under the name of Nemex 2 (for dogs). Same stuff as the vet uses to treat cats, but diluted, so you will need to administer more of the liquid to get the same dose. Follow the same dosage instructions (by weight) as for dogs and puppies. There’s also a powder you can mix into their food, called Panacur (by prescription only). NOTE: I don’t recommend products that use piperazine, which you will find in pet stores. Though labeled for kittens over 3 months, I know several people who treated older kittens with these medications, and the kittens died. There are some confirmed cases online, and my vets admit they have heard the buzz. Before I was aware of this danger, I did try it with my own cats. It made them vomit and gave them gas, but it didn’t get rid of the worms! So my opinion is that you should try to stay clear of these products.

The dosage is 5 ml for 10 lbs or 1 ml for 2 lbs this is a more dilute form of StrongID
