I had no idea these drops we’re harmful. I bought and used some on my dog and my cat a couple months ago. Neither had a negative response. I used them again last night for the second time on both my dog and cat. My dog has had no negative reaction. My cat began to have a bad seizure late last night. I didn’t think he was going to make it. He had cluster seizures through most of the night. Being New year’s Eve and New year’s day the vet was not open and I cannot afford an emergency vet. He relaxed this afternoon for a couple of hours and he seemed as if he was going to come out of it. I washed all of the drops off of his neck after I linked his seizures to the drops by finding a lot of articles on the web including this talking about pets dying from this stuff. Unfortunately, he seized again tonight and I’m not sure if he is going to make it. If he even makes it through the night, I may have to take him to the vet and have him put to sleep out of mercy. When he tries to stand up, he falls over. I’m afraid he has neurological damage from the grand mal that he started with and I think he has had at least one more that would at least border on a Grand Mal. This cat is one of my babies. I recently became an empty nester. My pets are my company. I am heartbroken. I had no idea that stuff could do this. How does a company get away with making and selling a product that kills the wonderful creatures it is supposed to help?? It is unconscionable.
