Cat Twitching In Sleep Seizure. Is your cat having a seizure or a normal twitch in the sleep? Cats twitch in their sleep due to signals sent to the brain during the rem (rapid eye movement) phase of sleep.
You may see the toes, ears, and nose twitch, as well. Fhs, or rolling skin disease, may be causing your cat’s skin to twitch along its spine as it sleeps. If your cat’s body stiffens up completely while he twitches, this is something to inform your veterinarian about.
