My cat Percy has been suffering from fleas for the past three months, and I decided to try Hartz Ultra Guard Plus. I applied it to him almost two hours ago, and immediately he started blinking repeatedly, wincing and acting strangely. I searched for cat negative reaction to flea medication, and this website was the first result. I panicked and have given him two baths. He’s eating and drinking water now, and isn’t showing any of the strange reactions from before.
Thank you all so much for opening up and sharing your stories, because you just saved my Percy’s life.
