Flea infestations - don't do diatomacious earth unless you want your entire house covered in white powder. Nor orange oil unless you want to burn them badly.
And the answer for many skin conditions in cats is brushing and then aloe from an aloe plant applied to the skin. Works like a charm. I will be trying the Apple Cider Vinegar for their remaining fleas. Thanks so much for that.
