When I read about pets and parasites in Hulda Clark's books a few years ago, I took thought 'Yikes'! When our cats passed on, I did not think that we would get more; however, three years ago, we bought two beautiful Maine Coon cats.
I believe that the dosage is 1 drop per pound for MH's Dewormer, but perhaps someone would have the correct number; you would increase to the correct amount slowly. I must confess that I have done nothing about this for my own 'girls', but must soon begin.
Since parasites are everywhere, just address the problem. Your enjoyment of and your love for your animals is important to your life and health.
