last week one of my cats died after using hartz spray on him, another cat i used the product on went to the vet with bad burns, it actually looked like his skin was melted off in places. The vet asked me if i had used hartz on him i said yes, he then told me about all the animals that have died or become sick from using this product. If i had been aware of this i never would have used the product and Inky would still be here today. The public needs to be more aware of the dangers of using this product, and the product should not be on store shelves. My other cat Yella is much better he still has a few burns and acts different than he did before he got sick, but he is expected to make a full recovery.
