I have three cats, all different breeds and age who all have one itchy ear that is driving them crazy, the scratching to get to this itch makes them howl! We checked them all and they do not have mites or any other bugs or such thing. I was wondering if there is something out on the market or maybe a home made type thing that we can do to relieve them of this itch since we can not afford to bring them all to the vet at this time.
