I was at the vet with my cat today and while I was in the treatment room the receptionist interrupted with an urgent call from a frantic cat owner. She had put Hartz drops on her cat and he was having a violent reaction to it. He recommended she wash the cat immediately with a strong detergent that would remove the product.
After the receptionist left I asked him about Hartz drops. I had read online about the dangers but had no firsthand information. He told me the drops often caused extremely violent reactions in cats. I was apalled that his product remains on the market and I’m making sure that everyone I know who loves animals knows about it.
