Highly recommend and I believe a must-have to keep around at home as preparation just in case...Go for it! It's the best,natural herbal complex/combination I have come across in this category(without fillers, sugary syrup bases,colours and whatnot).Used it with 4 cats and 5 stray dogs when there was a tick fever scare around and while all of them had a different blood panel reading and temperatures with infection.Some of the cats were in heat too.I used a tiny quantity with each of them-their temperatures normalised and they began looking more like their normal,healthier selves real quick.Ticks all boxes.So relieved and so grateful!
