I gave my cat a new flea tick medication on December 22nd and on the 29th he had a short seizure for the first time. He was put on prozac a month prior to that so we thought it was the prozac that was causing it. I called our vet and we have been weaning him off the Prozac. He is continuing to have seizures and with some research we realized that its most likely poisoning from the flea medication. We have bathed him, but since it happened 3 weeks ago do we need to take to him to the vet?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Toxicity from flea products usually lead to tremors/seizures that don't stop right away, they often continue. If your cat had a quick seizure (lasting about 1 min and then stopping completely), then this was likely unrelated to the seizure medication. Also, if the seizure stopped, then unless you re-apply the medication, it should not occur again. It is possible that your cat is having seizures for different reasons then the medication. If your cat was tremoring for a bit of time that slowly resolved (over many hours or even days), and is now stopped, and hasn't occurred again, this could be from the medication, and no intervention is required, just don't use that medication again. Best of luck with your little one!
