The vet agrees with our 'diagnosis' of partial seizure/petit mal' but, of course, has no idea what might have caused it. Everything was AOK on examination today.
Sky recovered fully within a few minutes, so that seems to exclude a vestibular stroke, thankfully.
The options were to start investigations with blood tests or to put steroids back to previous dose and watch/wait. Given Sky's extreme nervousness, I opted to increase the steroids and watch. So she will go back to 1/2 tab on alternate days, which is not a huge dose considering she had 1/2 tab twice a day for more than a year. We can put does up again if she has any further 'events'.
Madam has had a bit to eat and is hiding out under our bed. I hope/expect she will slink out later on, fingers crossed she will come to me for a fuss.
Like many people, I don't handle uncertainty well and like to think I am in control of my life. Sky is a real lesson in uncertainty; in taking each day as it comes and not worrying what the future may bring!
