I have an 11 year old cat named Gizmo. The other day we gave her a flea treatment from Hartz and later that night she was having sseizures almost every hour sometimes a little quicker. Shes at the vets now and if she does not improve in 24 hours we will be forced to put her down. I have had this cat since i was six and nothing pains me more than seeing her in this condition. Its just not right and this has to stop.
