Two months ago, I went to put the flea medication on my cat, Pinky (10 years old), I didn't have my glasses on and just reached on top of the refrigerator like I always do. I put it on her and that was that.
The next day when we came home from work, Pinky was shaking and almost in seizures. I rushed her to the Vet Hosp. and they said right away, you must have given her dog flea medication. I couldn't believe that I could have made such a mistake. They started an IV on her and said they would be giving her several baths and working on her but not to worry, cats don't usually die from this. At 1am, the Vet called and said that Pinky had "coded" three times and could they let her go. I was so devastated. I killed my beloved cat out of pure stupidity. Now I tell everyone, if you have dogs and cats, don't get the flea medicine mixed up.
