If it was just the revolution it should have at least calmed calmed dow after one month but as I discovered the revolution exacerbated what were mild ataxia and seizures in Bramble into full blown seizure with involuntary motor movements - he muscles were rigid and he was terrified. Luckily after standing my ground with vets he improved for a while. The most severe time time is 14 hours after revolution is put on the skin - that is when it is most potent, And then it is in th esystem for upto 4 weeks. Bramble too had an FIP looking belly. Do your acts pupils dilate during this - test if they repond to light. Does you r cat ever appear blind or partially blind at any time and how often is this seizure activity happening. Have you been on the epi-felines groups to ask them about seizures - if not get on there. The more input you get the better.
