The little old lady thought she was helping her cat by applying Hartz Flea treatment, little did she know that her cat would have a severe toxicity reaction to it. The cat started to have severe seizures despite treatments of diazepam, and phenobarb to stop the seizures. The old lady brought her to us, the vet hospital. They eventually stopped however the next day she was nearly comatose, however conscious. Day 3 she was sitting up and eating, we thought she’d be ok. Day 4 the seizures started again, only this time she didn’t respond to diazepam, phenobarbitol injectable, methocarbimole or isoflorane anesthetic gas. We eventually after 3 hours of trying everything in our power to save her, had to euthanize her.
