I put hartz flea drops on my cat Precious this a.m. , My family and I left to go shopping and returned to our cat that was having severe seizures. I immediatly decided it had been caused by the flea drops. I called the vet and explained what was going on and he told me that this is a frequently occuring event after using the Hartz flea drops. As I type this, Precious is at the vet recieving antiseizure medication along with IV’s. The vet said he would be spending the night with our Precious to monitor her closely.We will all say a prayer for her tonight that she will get over this. I hope that I can spread the word to thousands of other pet owners, so their animals will not have to suffer like these other animals have suffered.
