Did my kitten have a seizure?

We just brought home a kitten an hour ago and everything seemed to be fine. As I was crawling over towards it, it stopped and looked scared and started to shake. Its eyes were focused forward, but at nothing particular. After a few seconds its ears went back and started to twitch rapidly, and it started to drool from the side of its mouth. It was still standing on its four paws, and this lasted about 10 seconds before the cat returned to normal. A few meows and it was back to playing.

I’m worried this kitten had a seizure – it did have a stressful day of vet/vaccines/dewormer and a new house. Is it likely this was a seizure? If so, is it likely to recur? I’m wondering if I should take the kitten back.
