Apple Cidar Vinegar
My experiment with ACV has turned out very successfully. This was the first summer/fall that none of my outdoor cats had ear mites and I didn't find a single tick on any of them. Their coats even seem shinier. As well as the 6 cats, we also have two labs (indoors) and I put a tbls. of vinegar in their water each day.
The vinegar must be natural and not pasteurized with the 'mother' in it. I am thrilled with these results because treating all of these ears was always a chore in the past. Also, none of the animals has had worms this year. The cats and dogs all eat an occasional rodent (actually, some of the cats eat lots!) so worms used to always be present.
BTW, all of our animals are spayed/neutered. Cats are added when they appear. We do have plenty of coyotes around here but I find that once the cats reach a year old, they seem to be very 'street smart'.
