How to dose pyrantel pamoate for your cats and kittens by weight?
What an adorable kitten!! Each ml of the drug contains 50mg of the pyrantel base, and the dose for pyrantel pamoate is 5mg/kg. Here is how to figure it out:
Body weight in pounds divided by 2.2 gives you the body weight in kg.
For example, a 12 pound cat is 5.45 kg.
Then, take the kg weight and multiply it by 5 -- in the example above, the 12 pound (5.45 kg) cat would get 27.27 mg of the pyrantel.
Since each ml contains 50 mg, take 27.27 and divide by 50......27.27/50 = 0.54 ml.
12 pound cat = 0.54ml
10 pound cat = 0.45ml
2 pound cat = 0.09ml
Be sure to dose them again in two weeks to make sure all the worms are killed. I hope this helps!
