Is my kitten dreaming or seizing? Twitches, open mouth, head back.

If Willow twitches only when she sleeps, she is having a lot of wild dreams. Thiis is nothing to worry about. It is also a sign that she is feeling very safe, so she can sleep very deep. She is likely having great adventures in her sleep, catching mice and playing. No worries!

If you can wake her up and the shaking stops it is not a seizure and is more likely movement associated with REM sleep. If you try to wake her up but she continues to have muscle tremors it could be a seizure or neurologic disorder and you should see your veterinarian. If you do decide to see your veterinarian a video can help them determine what might be going on.

If you can wake her up when this occurs and she seems normal then this is probably a nightmare or dream. If you attempt to wake her and it doesn't stop I'd be concerned that this might be seizure activity. If it seems a seizure is more likely I'd recommend making an appointment to see your vet.

Poor Maui!! I understand your concern for him. This definitely could have been a seizure, the decreased energy you are now noticing could be the post-ictal or post-seizure phase. Being completely relaxed such as during sleep can lower the seizure threshold for some animals. I would recommend that Maui be examined by your regular veterinarian. They may want to do some diagnostics (such as X-rays, blood work and a fecal exam) to rule out some conditions that may contribute to seizures. Your vet likely will not recommend any medications or treatments at this time, it is important to determine if this is a once off incident or if Maui is going to be prone to seizures long-term. I would recommend keeping a log of ahyvsusosct activity, especially any physical symptoms (such as limb paddling), and also duration of the episode.

This almost sounds like focal seizure activity - sometimes cats will foam at the mouth and make chewing motions during a seizure. I'm wondering if her eyes seem different because she is actually unconscious during these episodes. Of course ingesting something that tastes bad could also cause something like this but it seems unusual for it to happen more than once. I'd recommend having a vet examine Mao Mao - if you can get a video of the episode it could help your vet determine what's going on.

She needs to be examned by a vet to determine the cause. It could have been a seizure but could also be caused by a heart problem, like cardiomyopathy. Your vet can do a workup to diagnose and then determine if treatment is needed.

Mama Kitty sounds quite ill. Repeated abnormal neurological behaviors could be due to a seizure (which can raise the body temperature significantly to the point of causing brain swelling/damage), infectious diseases, toxins (although you report that this didn't occur), among others. Since she has such a high fever and is repeatedly having these abnormal behaviors, Mama Kitty should be examined by a vet immediately and will likely require hospitalization to monitor and attempt to resolve her high fever. I hope that she's on the mend soon!
