Unfortuantely no one told me the affects of Hartz flea medicine. I’m college student and saw that it was so much cheaper than Advantage so I got it. The first time I used it in Dec. 2003 my cat went into seizures and had to be rushed to emergency costing me hundreds of dollars. I thought for sure she was gone. I found out today by my roommate that there was a lawsuit out and that I could possible sue because I have documentation on this. Does anyone know how I would go about doing this and finding out more info? I would greatly appreciate it! It disgusts me to find that this has happened so much and that it’s still available in stores. Thank you.
