# Why Do Cats Twitch in Their Sleep? Normal or Seizure? Is it normal for cats to twitch in their sleep? Yes, in most cases it is completely normal. Cats cycle through REM sleep just like people do, and small muscle jerks, whisker flicks, and paw paddling are a normal part of that stage. The tricky part is knowing when twitching is just dreaming and when it might be a seizure. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Mild twitching during sleep is normal. It happens during REM sleep, the stage where dreaming occurs, and it usually stops within seconds or when you gently wake your cat. - Normal twitching is small and quiet. Look for twitching ears, whiskers, paws, or facial muscles, sometimes with quiet chirps or suckling motions. - A seizure looks different. It often involves stiffening, paddling that does not stop when you touch your cat, loss of bladder or bowel control, drooling, or a period of confusion afterward. - Film it. A short video on your phone is one of the most useful things you can bring to a veterinary visit, because most episodes are over before you reach the clinic. - Get help fast if an episode lasts more than a few minutes, repeats in clusters, or your cat does not fully recover between episodes. ## What Cat Twitching While Sleeping Usually Looks Like Most sleep twitching is subtle. You might see your cat's whiskers flick, her ears rotate, her eyelids flutter, or her paws curl and uncurl. Some cats make small sucking or chirping sounds. Others look like they are running in place. These movements happen during rapid eye movement (REM) sleep. REM sleep is the stage where the brain is highly active and dreaming occurs, and it is marked by brief muscle twitches and rapid eye movements [1]. In mice, researchers have recorded bursts of activity in the thalamus, a deep brain region, during REM sleep that line up with these twitches [1]. The same general process happens in cats. The key feature of normal twitching is that it is brief and easy to interrupt. If you softly say your cat's name or touch her gently, the twitching usually stops and she either wakes up or shifts position. She does not look distressed afterward. ### Is it normal for kittens to twitch in their sleep? Yes. Kittens twitch in their sleep just like adult cats, and often more visibly. Their nervous systems are still developing, and they spend a larger share of their time in REM sleep than adult cats do. Frequent, small twitches in a kitten who is eating, playing, and growing normally are not a cause for concern. ## Main Causes of Twitching in Sleeping Cats Twitching has several possible causes, and most of them are harmless. The table below gives a quick comparison. | Cause | Typical clues | How urgent | |---|---|---| | Normal REM sleep behavior | Brief twitches of face, ears, whiskers, or paws. Stops when you touch your cat. No confusion afterward. | Not urgent | | Dreaming with movement | Looks like running, hunting, or suckling. Happens during sleep only. | Not urgent | | Myoclonus (muscle jerks) | Sudden, shock-like jerks, often of the head. Can happen while awake. Older cats are more often affected. | See your vet soon | | Medication-related jerks | Starts after a new medication. Short head jerks that look different from the cat's usual seizures. | Call your vet | | Seizure activity | Stiffening, paddling, drooling, loss of bladder control, confusion afterward. | Emergency if prolonged or repeated | ### Normal REM sleep behavior This is by far the most common reason. The brain is active, the body is mostly still, and small twitches leak through. Your cat is fine. ### Myoclonus Myoclonus is a sudden, brief muscle jerk. A 2025 study described 15 older cats with spontaneous late-onset myoclonic epilepsy. All 15 had jerks of the head, and some also had jerks in the front legs or the whole body [2]. The median age at presentation was 13.2 years, and the jerks tended to become more frequent over time [2]. Two of the 15 cats also had generalized tonic-clonic seizures [2]. This matters because myoclonus can happen while your cat is awake, not only during sleep. If you see head jerking when your cat is standing, eating, or walking, that points away from simple dreaming. ### Medication-related jerks Some medications can trigger muscle jerks. A 2024 report described two cats with chronic kidney disease and a history of seizures who developed short, intermittent head jerks after receiving gabapentin at doses of 11.8 to 16.4 mg/kg [3]. The jerks looked different from the seizures the owners had seen before [3]. If your cat starts jerking after a new medication, tell your veterinarian. ### Seizure activity Epilepsy is one of the most common neurological disorders in cats, affecting 1% to 2% of the feline population [4]. Many cats with epilepsy do well on standard anti-seizure medication, though a small number have drug-resistant seizures [4]. Seizures in cats can be generalized, meaning they involve the whole body, or focal, meaning they start in one area [4]. A seizure that happens during sleep can be hard to distinguish from a dream at first. The differences are covered below. ## Cat Twitching vs Seizure: How to Tell the Difference This is the question most owners really want answered. Here is what to watch for. **Normal twitching:** - Small, localized movements (ears, whiskers, paws, face) - Stops within seconds when you touch or call your cat - Your cat wakes up normally and seems fine - No drooling, no vocalizing in distress, no loss of bladder or bowel control - Happens only during sleep **Seizure:** - Whole-body stiffening, then rhythmic paddling or jerking - Does not stop when you touch or call your cat - Drooling, chewing motions, or foaming at the mouth - Loss of bladder or bowel control - A period of confusion, pacing, or blindness after the episode - Can happen while awake The recovery period is one of the most useful clues. After a seizure, many cats are disoriented, wobbly, or unusually quiet for minutes to hours. After normal sleep twitching, your cat simply wakes up and goes about her day. If you are not sure which one you saw, film it. A video lets your veterinarian see the exact pattern, which is far more useful than a description. ## Red Flags That Make It an Emergency Call an emergency veterinary hospital right away if you see any of these: - A seizure that lasts more than 5 minutes - Two or more seizures in a row without your cat fully recovering in between - Trouble breathing during or after an episode - A seizure that happens in water or near something that could cause injury - Your cat does not wake up or remains unresponsive - Repeated episodes that are getting closer together If your cat is having a seizure, do not put your hands near her mouth. Cats do not swallow their tongues, and you can be bitten badly. Clear hard objects away from her, dim the lights, and keep her cool. For step-by-step guidance, see [What to Do If Your Cat Has a Seizure: Medication and Emergency Response](/knowledge/veterinary-medicine/pet-medication-guide/cat-seizure-emergency-response). ## What You Can Do at Home While You Wait If the episode has passed and your cat seems normal, you have time to gather information. - **Write down what you saw.** Note the time, how long it lasted, which body parts moved, and how your cat behaved afterward. - **Film future episodes.** Keep your phone within reach at night. - **Check for triggers.** Note whether episodes happen at a certain time, after a dose of medication, or around stressful events. - **Keep a log.** A simple notebook or phone note with dates and descriptions helps your veterinarian spot patterns. - **Do not change medications on your own.** Never start, stop, or adjust a seizure medication without veterinary guidance. If your cat's breathing seems unusually fast or labored during sleep, that is a separate concern worth checking. See [Cat Breathing Fast While Sleeping: When to Worry](/knowledge/veterinary-medicine/vet-visit-decisions/cat-breathing-fast-sleeping-worry). ## What Your Veterinarian Will Check and Test Your veterinarian will start with a full history, including the video you brought. Then comes a physical and neurological exam. The neurologist or veterinarian is checking your cat's reflexes, balance, vision, and awareness. Blood work is usually next. This checks organ function, blood sugar, and other values that can cause or worsen neurological signs. Because kidney disease appeared in both cats with gabapentin-related jerks [3], kidney values are often part of the picture. Your veterinarian may also recommend: - **Advanced imaging** such as MRI, to look for structural causes. In the myoclonus study, eight of 15 cats had advanced imaging that was normal [2]. - **Electroencephalography (EEG)**, which records brain electrical activity. EEG is an important tool for classifying feline epilepsy and can help distinguish seizure types [4]. - **A medication review**, especially if jerks started after a new drug [3]. If your cat is diagnosed with epilepsy, treatment usually starts with standard anti-seizure medication. Your veterinarian will calculate the dose based on your cat's weight and health. Some cats need adjustments over time, and a small number have seizures that do not respond well to standard drugs [4].

It is a sign of healthy sleep. What you can do is monitor for change. Twitching that becomes stronger, longer, or more frequent deserves a veterinary visit. So does twitching that starts happening while your cat is awake. Keep up with routine veterinary care, give medications exactly as prescribed, and bring your log and videos to every visit. If your cat is older, pay attention to new head jerking, since late-onset myoclonus tends to appear in cats around 13 years of age and often becomes more frequent over time [2]. A calm, consistent home routine also helps. Stress can lower the seizure threshold in some cats, so predictable feeding, play, and sleep schedules are reasonable steps. If your cat is vocal at night, that may be a separate issue. See [Why Is My Cat Crying at Night?](/knowledge/veterinary-medicine/behavior/why-is-my-cat-crying-at-night). And if you notice ear twitching while your cat is awake, that has its own list of causes: [Cats Ears Twitching And Shaking Head](/knowledge/veterinary-medicine/clinical-methods/cats-ears-twitching-and-shaking-head). ## Limitations and When to Contact a Veterinarian No article can tell you what is happening in your individual cat. Only a veterinarian who examines your cat can do that. **Contact a veterinarian the same day if:** - Twitching or jerking starts happening while your cat is awake - Episodes are becoming more frequent or more intense - Your cat seems confused, wobbly, or "not herself" after episodes - Jerking started after a new medication - Your cat is older and has new head jerking **Go to an emergency hospital now if:** - A seizure lasts more than 5 minutes - Seizures repeat without full recovery in between - Your cat has trouble breathing - Your cat does not wake up or stay responsive **Schedule a routine visit if:** - Twitching is mild and only during sleep, but you want reassurance - You have video you would like reviewed - You want to discuss whether your cat's episodes need testing ## Frequently Asked Questions ### Should I wake my cat if she is twitching in her sleep? No, there is usually no need. Normal sleep twitching is harmless, and waking your cat interrupts healthy sleep. If you are worried about a specific episode, gently call her name and watch whether she responds normally. If she does not respond or the movement continues, treat it as a possible seizure and contact your veterinarian. ### Can a cat have a seizure while sleeping? Yes. Seizures can happen during sleep, and they can be mistaken for dreaming at first. The clues that point to a seizure include whole-body stiffening, paddling that does not stop when you touch your cat, drooling, loss of bladder control, and confusion after the episode. If you see these signs, film what you can and call your veterinarian. ### Do older cats twitch more in their sleep? Not necessarily more, but older cats can develop new muscle jerking that is different from normal sleep twitching. A study of 15 cats with late-onset myoclonic epilepsy found a median age of 13.2 years at presentation, with head jerking in every cat. Some also had jerking in the front legs or the whole body. New jerking in an older cat is worth a veterinary visit. ### Can medication cause my cat to twitch? Yes, in some cases. A report described two cats that developed short head jerks after receiving gabapentin, and both had chronic kidney disease and a prior history of seizures. The jerks looked different from their usual seizures. If your cat starts twitching or jerking after starting a new medication, contact your veterinarian before giving another dose. ### How long does normal sleep twitching last? Normal twitching usually lasts a few seconds to a minute and stops on its own or when your cat is gently disturbed. It tends to come and go in bursts during REM sleep. Twitching that continues for several minutes, involves the whole body, or does not stop when you touch your cat is not typical and should be evaluated. ## Related Articles - [Why Is My Cat Crying at Night?](/knowledge/veterinary-medicine/behavior/why-is-my-cat-crying-at-night) - [Cats Ears Twitching And Shaking Head](/knowledge/veterinary-medicine/clinical-methods/cats-ears-twitching-and-shaking-head) - [What to Do If Your Cat Has a Seizure: Medication and Emergency Response](/knowledge/veterinary-medicine/pet-medication-guide/cat-seizure-emergency-response) - [What Are the Side Effects of Seizure Medication in Cats?](/knowledge/veterinary-medicine/pet-medication-guide/seizure-medication-side-effects-cats) - [Cat Breathing Fast While Sleeping: When to Worry](/knowledge/veterinary-medicine/vet-visit-decisions/cat-breathing-fast-sleeping-worry) - [Why Is My Cat yowling at night?
