I use grapefruit seed extract which I only purchase one product that imo is the best there is. It can be used for anything. I use it to heal wounds, it is also a disenfectant on surfaces. Great to put in a water pik for cleaning teeth and gums. I even use it on my face. It is very potent so only a few drops is needed in water. One bottle last forever.

Excellent recommendation. We use it for all manner of critters, and me too upon occasion ; )
May God guide our course.
