Sounds like seizures are not that uncommon and that it's a problem only if they have them close together and or lasting longer than 5 minutes. The fact that it has been years since the last one is a good sign. One good thing about animals and seizures is that 99% of the time, they are already on their side. That is the #1 thing that you do with a person is get them on their side. People are MUCH more prone to lay on their backs and choke to death on their tongues aspiration. Easy for me to say....But you cannot stress being at work if it happens. It can also happen when you are at home and asleep. The fact that she's on her side is huge.
