This past week end I gave my two cats (squeeky&dash) a dose of the Sergent Pretect flee and tick medicine because they were scratching there necks. One hour later I went looking for dash(6months old) and found him in my back room lying on the floor having what looked like a siezer, I then called my mother who has 3 cats and asked her what I should do. She told me to put him in the bath and try and wash it off, well this did not work and he had a heart attach. My husband had to give him a grave. I had thought that maybe it was my fault, that maybe I gave him to much. I only gave him a 1/2 dose. My oldest cat did not show any signs of this and we thought maybe the smallest must have gotten into something poison outside. We watched the oldest all day and she never acted like anything was wrong. We should have taken her to a vet but there was not one open on the weekend where I live. At 12:27am my husband and I heard a loud crash and went to look at what it was. My oldest cat was having the same problems as Dash. We did everything to help her survive, I even called the poison control to ask if my children were in any danger because they had picked the little one up once or twice trying to keep him from going outside (they did wash there hands). Poison Control assured me that it would not hurt them but my cat was not going to make it, he said to make her feel as comfortable as possible. Whe ended up makeing a grave for her at 2:37am. I cried for the next 2 days straight thinking it was my fault but now I know different. I just want everyone to know how dangerous it is to use some over the counter meds. Please talk to your vet first to keep this happening to your animals, and yes I would be more than happy to be apart of any lawsuit against meds like this one. Thank You for taking the time to read this.
