My cat was sleeping and her head started shaking. Was she dreaming or having a seizure?

My cat was sleeping and she started shaking her head a little. I'm just a little concerned. Could she be epileptic and have been having a seizure?

Some cats are very active when they sleep.  My cat Reilly meows and his legs will twitch sometimes when he is sleeping.  If it continues and you are concerned a visit to your vet never hurts

My cat also twitches in his sleep.

If you have video capabilities on your phone or otherwise, try to capture it so you can show a vet if you decide to go. Anytime something weird happens with my cat, I try to take a video on my phone to help my vet figure out what's going on.

i second trying to get video footage then you could also post here so people who have experience with epilepsy in cats can further tell what may be happening. hope your kitties are doing well

I agree with the above, a video on your phone and then show it to the vet. I have done this numerous times, so the vet knows exactly what I am talking about.
