My cat has been twitching as he falls asleep recently. His face and front paws go, almost as if he's having a dream, but he's at least half-lucid, so I'm pretty sure he's not dreaming. I was doing a fundraiser for Vets without Borders this weekend and I spoke to the vet tech that was there and she said that it could have been a small seizure. He recovers completely right after I jolt him awake with a sudden sound or something, and he acts completely normal otherwise.

Has this happened to anybody else? And should I rush to get him to the vet?
