Pet Seizures: What to Do During One and What to Tell Your Vet

Watching your pet have a seizure is a terrifying moment, and it can be hard to know what to do when it’s happening. While your pet is seizing, keep your hands away from their mouth, move anything hard out of the way, and note the time it starts. Once it is over, write down what you saw before the details blur, because your veterinarian will want to know whether this was the first episode, how long it lasted, how much time has passed since the last one, whether your pet could have reached a medication, plant, or chemical, and what seemed off in the days beforehand. A phone video is worth more than a description from memory, since some episodes are subtle and others turn out not to be seizures at all. A first seizure means your pet is seen the same day, no matter how brief it was or how normal they look now. What your notes change is which tests come first and whether treatment starts right away or after more information.

Your pet may still be disoriented and easily rattled by handling in the hours after a seizure, and that is what we plan around at Star of Texas Veterinary Hospital in Austin. As Austin’s first Fear Free certified practice, we can work with your pet on the floor, in your lap, or outside in one of our open-air exam spaces, and our Cat Friendly certification shapes how we handle a rattled cat. Call ahead and tell us a seizure happened so we can fit your pet in quickly and hear your account while it is fresh.

Seizure First Aid at Home: The Most Important Information

• Your only jobs during a seizure are clearing hazards away, keeping your hands clear of the mouth, checking the clock, and letting the episode run its course.
• Never give human pain medication or a leftover sedative to a pet who is seizing or recovering, and never try to hold the tongue or pry the jaw open.
• Five minutes is the line: an episode that runs longer, a second one within 24 hours, or a pet who doesn’t come back to themselves in between needs an emergency hospital right now.
• The wobbly, pacing, seemingly blind hour afterward is normal brain recovery, not a second crisis, and it usually clears on its own.

What Does a Seizure Actually Look Like in a Dog or Cat?

Most seizures in dogs and cats last under two minutes and follow a rough pattern: sudden loss of awareness, stiffening or collapse, paddling legs, drooling, chomping, and sometimes loss of bladder control. Plenty of episodes are far quieter than that, showing up as staring into space, twitching in the face or leg, or a repetitive snapping at nothing known as “fly-biting”. Both count as seizures.

Sorting a true pet emergency from a frightening but self-limiting event comes down to a few specifics: how long it lasts, whether it happens again, and how your pet looks in between.

Many episodes come in three parts. Some pets show a warning phase in the minutes beforehand, with clinginess, hiding, restless pacing, or staring at nothing. Then the event itself. Then a recovery stretch that can outlast the seizure several times over, called the post-ictal phase.

Seizures in cats often look nothing like the full-body event people picture, showing up instead as facial twitching, rippling skin along the back, sudden staring, or a few seconds of unresponsiveness. That’s why feline episodes get written off as a weird dream or a bug on the wall.

Not everything that looks like a seizure is one, either. Fainting from a heart rhythm problem drops a dog just as suddenly, but they’re usually up again within seconds. Vestibular disease brings stumbling, a head tilt, and flicking eyes while your pet stays aware of you the whole time. Tremor and shivering syndromes leave the pet fully conscious. Puppies and kittens twitch and paddle in deep sleep, which stops the second you say their name. Telling these apart takes time and a careful history, and we build our veterinary exams in Austin around exactly that.

What Should You Do While a Seizure Is Happening?

Your job while a seizure is happening is small and specific: clear hard objects out of the way, keep your hands away from your pet’s mouth, note the start time, and let it run its course. Dim the lights, move other pets out of the room, and watch closely without touching.

If your pet is on a bed or a couch, get them gently to the floor before the movement starts throwing them around. You can put a pillow or blanket between their head and the floor or furniture if they are close and might hit something hard. And put the time in your phone, not just in your head, because five minutes and ninety seconds feel identical when you’re scared.

A video settles whether this was a seizure at all and shows us which part of the body started first. Even a short, textbook-looking episode earns a visit, so call us and book a visit while the details are still sharp.

How Do You Help Your Pet Recover Once the Shaking Stops?

The hour or two after a seizure belongs to what’s called the postictal phase. Stumbling, pacing into walls, and temporary blindness after the shaking stops usually resolves on its own as the brain resets, often within minutes to a couple of hours.

Other postictal behavior surprises people: ravenous hunger, frantic thirst, howling or yowling, hiding, and not seeming to recognize the person kneeling next to them. A normally gentle dog can snap in this state, and a friendly cat can go flat-eared and defensive. None of it is personality. It’s a brain rebooting.

So keep the next stretch boring: low light, quiet volumes, no excitement. Block the stairs and keep them off decks and pool edges until the walking looks steady. Hold off on water until your pet can stand and swallow without weaving, then offer a small amount. Keep other pets away, since housemates often react badly to the smell and behavior of a pet coming out of a seizure. Sit nearby and talk quietly instead of hugging or hovering.

Stress can lower the seizure threshold, which is why the visit that follows shouldn’t undo the calm you just built at home. That’s the whole logic behind Fear Free handling for a pet whose nervous system has already had a rough day.

When Does a Seizure Mean Going Straight to an Emergency Hospital?

Status epilepticus, a seizure that won’t stop on its own, is where frightening becomes life-threatening. Any episode running past five minutes, back-to-back seizures with no real recovery between them, or more than one in a single day means the nearest 24-hour veterinary ER, not a phone call in the morning.

A pet who seizes after a hot Austin afternoon outside may be showing heatstroke rather than a primary brain problem, and that combination needs care right now instead of a wait-and-see hour.

We handle urgent visits while we’re open on weekdays, so call or text us before you head over and we’ll tell you whether to come here or drive straight to the ER. Evenings, weekends, and holidays, the 24-hour emergency hospital is the right call, and we’ll pick the case up from there.

What Causes Seizures in Dogs and Cats?

A seizure is a symptom, not a diagnosis. The electrical misfire can start from a variety of neurologic issues inside the brain, from epilepsy, a tumor, inflammation, or an old head injury, or from outside it, when low blood sugar, organ disease, a toxin, or overheating changes what the brain is swimming in. Age and species narrow that list fast.

• Epilepsy: Idiopathic epilepsy in dogs usually announces itself between six months and six years of age in a dog who is otherwise healthy and whose bloodwork comes back completely normal. Epilepsy in cats is diagnosed far less often than in dogs, which is why a seizing cat gets a harder search for an underlying cause before anyone settles on a primary seizure disorder.
• Structural brain disease: Tumors, strokes, encephalitis from infectious or immune-mediated causes, and scarring from an old head injury all irritate brain tissue enough to set off an electrical storm.
• Organ and metabolic disease: When the liver stops clearing toxins out of the bloodstream, the brain is the first organ to show it, so liver disease can surface as seizures, head pressing, or circling rather than any obvious stomach upset. Low blood sugar, advanced kidney disease, and low blood calcium do the same thing by a different route.
• Toxins: Dog flea products applied to a cat, certain household cleaners, and a handful of common plants sit near the top of the list for toxin-related seizures, which makes the history you can give us as valuable as any lab result. Xylitol, chocolate, marijuana, rodent bait, and spilled prescription pills belong on the same shelf of suspects.
• Puppies and kittens: The very young have their own short list, including low blood sugar in tiny breeds, a portosystemic shunt that routes blood around the liver, distemper and other infections, and fluid buildup in the skull. Any seizing puppy or kitten needs to be seen right away.
• Heat and head trauma: A body temperature that climbs too high or a hard knock to the skull can both trigger seizures in a previously healthy pet.

That range is exactly why your account of the episode carries so much weight, and why the veterinarians who sort through those possibilities start with your story before a single test is ordered.

How Do We Figure Out Why Your Pet Had a Seizure?

The workup starts with your account of the episode and any video, then a hands-on physical and a neurologic exam that checks reflexes, vision, and how your pet moves. Bloodwork, a urine sample, and a blood pressure reading come next to rule out causes that begin outside the brain.

Our in-house lab lets us run that first round of chemistry, blood counts, and glucose here rather than sending it out, which matters when a low blood sugar or a liver value changes the plan on the spot. Our team also uses diagnostic testing with x-ray and ultrasound to look for organ disease, masses, or heart problems that can drive episodes from elsewhere in the body.

Advanced imaging enters the conversation when the neurologic exam or your pet’s age points toward structural disease, since brain tumors never show up on bloodwork and are a common reason for a first seizure after age five. MRI and spinal fluid analysis aren’t performed here. When your pet needs either one, we refer to a veterinary neurologist and coordinate that referral for you.

The plan gets shaped around the individual. A healthy three-year-old Labrador with one brief seizure and clean labs is a very different conversation from a twelve-year-old cat with weight loss and a new head tilt.

Can a Dog or Cat Live a Normal Life on Seizure Medication?

Most dogs and cats on anti-seizure medication go right back to their walks, their windowsills, and their usual personalities once the dose settles. The realistic goal of managing seizures is fewer, shorter, and less severe episodes rather than zero forever, with medication doses guided by bloodwork on a set schedule instead of only after a bad night.

Phenobarbital, levetiracetam, zonisamide, and potassium bromide are the usual workhorses, sometimes alone and sometimes in combination. Sedation and wobbliness in the first week or two are common and usually fade. Recheck blood work watches organ values and, for some drugs, the level in the bloodstream, which is how the dose gets tuned to your pet rather than to a textbook. Some pets also go home with a rescue medication for cluster episodes, and whether that fits yours is a conversation worth having before you need it.

Never stop or skip an anti-seizure medication on your own. Abrupt withdrawal can trigger a severe cluster, so any change goes through us first.

The unglamorous home habits do real work here: dosing at consistent times, steady body weight, predictable routines, and avoiding the hottest part of an Austin afternoon. Keep a simple log with the date, time, length, and what preceded each episode, since patterns show up on paper long before anyone notices them from memory. For pets whose anxiety spikes around storms or visitors, our team handles behavioral medicine, and lowering that background stress belongs in the seizure plan too. When episodes stay frequent or severe despite honest effort, quality-of-life counseling is a conversation we’d rather open early and gently than late.

Seizure Questions Pet Families Ask Us Most

Does every seizure cause brain damage?

A single short seizure rarely leaves lasting harm. The real risks come from the long ones and the clusters, where body temperature climbs, oxygen drops, and brain cells take a hit, which is why the five-minute mark carries so much weight. Injuries from falling off furniture or down stairs cause more trouble than the electrical event itself in many cases. Repeated uncontrolled seizures over years can make future episodes easier to trigger, and that’s the main argument for treating sooner rather than waiting.

Why does my senior cat seize when I crinkle a foil wrapper?

Crinkling foil, clinking spoons, and tapping keyboards can set off feline audiogenic reflex seizures in senior cats, a recognized condition rather than a strange quirk of your cat’s personality. Older cats are the typical patients, and the episodes range from brief absence spells to full convulsions. Identifying the specific sounds and removing them from your cat’s daily soundtrack often reduces the frequency on its own. Bring your list of trigger noises to the appointment, since it genuinely shortens the diagnostic path.

Are puppies and kittens too young to have seizures?

Young pets absolutely can seize, and the causes skew differently than in adults. Low blood sugar in toy breeds and tiny kittens, a liver shunt, infections such as distemper, parasites, congenital malformations, and toxin exposure all sit near the top of the list. Because several of these move quickly, a seizing puppy or kitten is an immediate visit rather than a wait-and-watch. We fold neurologic checks and toxin-proofing conversations into puppy and kitten visits for exactly this reason.

You Won’t Be Sorting This Out Alone

The first seizure is the one that undoes you. Watching a dog or cat you love lose control of their body, then wander the kitchen not quite knowing who you are, is a lot to hold by yourself, and most families replay it for days afterward. Here’s the part worth holding instead: many pets who seize once never do it again, and most of those who need medication go on to live full, ordinary, nap-in-the-sunbeam lives.

Keep the log, take the video, and bring both to us. Star of Texas Veterinary Hospital in Austin will help you make sense of the pattern and decide what, if anything, needs to change. Schedule a visit after any seizure or seizure-like episode, and we’ll work through it together.
