If your pet has a seizure at home, the most important steps are simple: stay calm, move nearby objects out of the way, and resist the urge to restrain them or put your hand near their mouth. Watching it happen is one of the most frightening things an owner can experience, but knowing what to do in those minutes genuinely makes a difference. Most seizures in dogs and cats last under two minutes and stop on their own, but what happens in the minutes and hours after the episode matters as much as what happens during it. Certain signs, including a seizure lasting more than five minutes, multiple episodes in a single day, or a pet that does not return to normal within 30 minutes, mean it is time to be seen immediately.

At St. Petersburg Animal Hospital and Urgent Care, we give prompt attention to pets who have had a seizure, with same-day and walk-in availability. Our in-house diagnostics, including lab work and digital imaging, let us start building a picture quickly, whether we are looking at a metabolic cause or tracking a pattern that points toward epilepsy. If your pet has had a seizure, our urgent care can help sort out what is driving it, and our internal medicine expertise means your pet can receive long-term care to manage their seizures all in the same place. Give us a call to talk through what you saw and what comes next.

Seizures in Dogs and Cats at a Glance

  • Most single seizures are brief: under two minutes, stopping on their own without intervention.
  • Some are emergencies: a seizure over five minutes, or two or more in 24 hours, is a pet emergency.
  • The postictal period is normal: the confused, disoriented stretch afterward can last minutes to hours.
  • Video is invaluable: a short clip of the episode, when safe to record, tells us what no description can.

What Does a Seizure Look Like?

A seizure is a sudden burst of abnormal electrical activity in the brain, and what it looks like depends on which part of the brain is involved. A generalized seizure usually causes collapse, stiff or paddling limbs, loss of consciousness, drooling, vocalizing, and sometimes loss of bladder or bowel control. A focal seizure can be much subtler: a twitching face, a leg moving on its own, a dog staring at nothing, or a cat suddenly bolting from a noise no one else heard.

Many people do not recognize the subtler events as seizures at all, so watch for these patterns:

  • Pre-seizure (aura): restlessness, hiding, clinginess, whining, or pacing in the minutes before an episode.
  • The seizure itself: collapse, stiffening, paddling, chewing motions, vocalizing, drooling, or loss of bladder or bowel control.
  • Focal signs: facial twitching, repetitive blinking, head bobbing, fly-biting at the air, or sudden unexplained aggression or fear.
  • Postictal phase: disorientation, pacing, temporary blindness, bumping into furniture, increased thirst or hunger, or just acting off for hours.

If your pet has had any episode like these, even a brief one, it is worth a conversation, since subtle events often precede more obvious seizures and putting the pieces together early can change the plan. Sometimes pet owners miss the seizure itself and only see the post-ictal period, since it lasts much longer than the seizure. Our wellness care includes the kind of full exam that picks up patterns you may have written off as quirks.

What Should You Do During and After a Seizure?

When a seizure starts, your job is to keep your pet safe, not to stop the seizure. Time the episode and record a short video if it is safe, since those two pieces of information are the most useful things you can bring to the appointment. The table below covers both phases:

During the seizure After (the postictal phase)
Stay calm and note the start time Give space and quiet, expecting confusion for minutes to hours
Clear furniture, cords, and other pets away Block stairs and slippery surfaces until coordination returns
Dim the lights and reduce noise Offer water only when steady; hold food 30 to 60 minutes
Do not touch the mouth or restrain Keep other pets separated, since a disoriented pet may lash out
Record a short video if you safely can Avoid sudden movements and loud sounds
Note loss of control, vocalizing, limb movement Write down time, duration, triggers, and recovery length


A first-time seizure always warrants a call, even if your pet seems back to normal, and coming straight in the same day is often the fastest way to start the workup. If your pet has had seizures before and this one fits the usual pattern, document it and let us know, since patterns matter for adjusting management.

When Does a Seizure Become an Emergency?

Most single seizures stop within two minutes and do not require an emergency visit that night, though they always warrant follow-up. A seizure becomes an emergency when it crosses certain lines, and status epilepticus, a seizure that will not stop, is life-threatening and needs immediate care. Signs that mean do not wait:

  • The seizure has lasted more than five minutes: call ahead and head to the nearest open facility.
  • Two or more seizures within 24 hours, even if each is brief, which signals cluster seizures.
  • A first-ever seizure, no matter how brief.
  • Suspected toxin exposure like chocolate, xylitol, certain plants, rodenticides, marijuana, prescription medications, or unknown ingestion.
  • Heat as a possible trigger, since a pet out in Florida heat before a seizure needs to be cooled and seen immediately, given the heatstroke risk.
  • No recovery within an hour, or coming out of one seizure only to start another.
  • Bleeding, severe injury, or breathing trouble during or after the episode.

We see urgent cases Monday through Saturday with same-day and walk-in availability, and life-threatening emergencies are referred to the nearest 24-hour facility when needed. If you are unsure whether what you saw qualifies, call us and describe it, since we would rather tell you it can wait until morning than have you wait and wish you hadn’t.

What Causes Seizures in Dogs and Cats?

Seizures are a symptom, not a diagnosis, and the underlying causes range from genetic conditions to toxins to systemic illness. In dogs, the most common cause of recurring seizures in otherwise healthy adults is idiopathic epilepsy, a genetic condition that typically appears between one and six years of age, while in cats epilepsy is less common and seizures more often point to an identifiable underlying cause. Common categories:

  • Idiopathic epilepsy, a diagnosis of exclusion made after other causes are ruled out, most common in young to middle-aged dogs.
  • Structural brain disease, including tumors like brain tumors, inflammation, trauma, or congenital malformations, more common in older pets with new-onset seizures.
  • Other neurological issues like encephalitis, meningitis, and degenerative conditions.
  • Metabolic and systemic illness, including liver disease, kidney disease, low blood sugar, thyroid disease, and electrolyte imbalances.
  • Toxin exposure, where toxin-related seizures in cats often involve dog flea products, essential oils, lily ingestion, or human medications, and dogs are commonly exposed to chocolate, xylitol, marijuana, and rodenticides.
  • Infectious disease, including tick-borne illness, fungal infections, and viral diseases that affect the brain.
  • Feline audiogenic reflex seizures, triggered by high-pitched sounds, are a recognized syndrome in older cats.

The age at the first seizure is one of the biggest clues: a three-year-old Labrador with a normal exam is statistically likely to have idiopathic epilepsy, while a twelve-year-old cat with new-onset seizures needs a different workup entirely.

How Do We Evaluate a Pet After a Seizure?

A diagnostic workup starts with the story: what came before, what the episode looked like, how long it lasted, how long recovery took, and whether toxin exposure is possible. From there it typically includes a thorough physical and neurological exam, bloodwork, urinalysis, and blood pressure measurement. What we can do in-house:

  • Complete physical and neurological exam, where reflexes, cranial nerve function, gait, mentation, and posture show whether the brain itself is involved.
  • In-house bloodwork and urinalysis, covering liver enzymes, kidney values, blood glucose, electrolytes, thyroid screening, and a complete blood count.
  • Digital radiography, where chest and abdominal X-rays screen for underlying disease, tumors, or organ changes.
  • Abdominal ultrasound, for a closer look when metabolic or organ disease is suspected.
  • Blood pressure measurement, since both high and low pressure can be relevant.

When the workup points toward a structural brain problem, most often in older pets or pets with deficits between seizures, advanced imaging like MRI or CT and cerebrospinal fluid analysis are typically next at a referral neurology service. Our internal medicine approach is step-by-step rather than every-test-just-in-case, and we explain the reasoning behind each recommendation.

How Are Seizures Treated and Managed Long-Term?

Treatment depends on the cause. A metabolic cause means treating the underlying disease, and the seizures usually resolve once the primary problem is managed, while toxin-related seizures are treated as emergencies with decontamination and supportive care. For idiopathic epilepsy or recurring seizures without a structural cause, the goal of long-term seizure management is to reduce the frequency and severity of episodes, not necessarily eliminate them entirely. Ongoing management usually involves:

  • Anti-seizure medication tailored to your pet, such as phenobarbital, levetiracetam, zonisamide, or potassium bromide, chosen by species, other conditions, and seizure behavior.
  • Routine bloodwork to monitor drug levels and organ function, since most anti-seizure medications require periodic monitoring.
  • A seizure log recording date, time, duration, triggers, and recovery, which tells us whether treatment is working.
  • Consistent routines and reduced stress, since predictable feeding, exercise, and sleep often mean fewer episodes.
  • Trigger awareness for pets where stress, loud noises, missed doses, or illness are recognized triggers.
  • Emergency rescue protocols, including a home medication to break a cluster before it becomes an emergency for prone pets.

Many pets with well-managed epilepsy live full, normal-length lives, and the realistic goal is fewer, shorter, and more predictable episodes. We adjust the plan as needs change, and if a pet reaches a stage where quality of life is the question, our team can guide that conversation.

Frequently Asked Questions About Seizures in Pets

Should I Take My Pet to the ER for a Single Short Seizure?

If it is the first seizure your pet has ever had, yes, even if it was short and they have recovered, since a first-time seizure always warrants evaluation for underlying causes. If your pet has known epilepsy and this seizure fits their usual pattern, document it and call the next day rather than necessarily making an after-hours visit. When in doubt, call and describe what you saw.

Can I Give My Pet Anything at Home to Stop a Seizure?

Not unless your veterinarian has specifically prescribed a rescue medication and shown you how to use it. Do not put anything in your pet’s mouth during a seizure, including water, food, or human medications, since most over-the-counter remedies are dangerous for pets and some human seizure medications are toxic to cats specifically.

Will My Pet Have Brain Damage From a Seizure?

A single short seizure under two minutes does not typically cause brain damage. Prolonged seizures over five minutes and cluster seizures can cause damage from sustained electrical activity, high body temperature, and oxygen deprivation, which is why those situations are emergencies. Getting recurrent seizures under control with medication helps prevent the cumulative effects of frequent episodes.

Are Certain Breeds More Likely to Have Seizures?

Some are. Idiopathic epilepsy has a genetic component, and breeds with higher rates include Beagles, Labrador Retrievers, Golden Retrievers, German Shepherds, Boxers, and Border Collies. That said, any breed and any mixed-breed dog or cat can develop seizures, so breed predisposition is one piece of the picture rather than the whole picture.

Seizures Are Frightening, But You Have Tools

Watching your pet have a seizure is one of the harder things to experience as an owner. The good news is that the actions that matter most, staying calm, keeping your pet safe, timing the episode, and knowing when to come in, are simple and learnable, and many pets with seizures, including those with epilepsy, live long, comfortable lives with the right management plan.

If your pet has had a seizure, keep a record of what you saw and reach out. We are family-owned and built on the idea that veterinary care should be understandable, accessible, and built around real conversations with the people who know their pets best. Call us to talk through what happened, or come in for urgent care if your pet needs to be seen the same day.
