Cat Seizures & Epilepsy – Vet Guide 2025 ⚠️🐱

By Dr. Duncan Houston BVSc

A seizure in a cat is a sudden burst of abnormal electrical brain activity that disrupts normal motor control, consciousness, or behavior. In 2025, veterinary neurology emphasizes speedy recognition, emergency care, accurate diagnosis, and tailored treatment—even lifelong when needed. This comprehensive guide covers seizure types, causes, first aid, diagnostics, medications, monitoring, prevention, and lifestyle support—including tools from Ask A Vet, Woopf & Purrz to help your cat thrive. 🧠❤️

1. What Are Seizures & Epilepsy?

Seizures—single events of brain misfiring—vary in severity and duration. **Epilepsy** is diagnosed when seizures recur, generally ≥ 2 events :contentReference[oaicite:3]{index=3}. Most seizures in cats are **symptomatic**—caused by brain disease—while **idiopathic epilepsy** is rarer :contentReference[oaicite:4]{index=4}.

2. Types of Seizures

• Pre-ictal (Aura):

Behavioral changes like hiding, vocalizing, drooling, or staring before a seizure begins :contentReference[oaicite:5]{index=5}.

• Ictal Phase:

• Generalized (grand mal): Total loss of consciousness, paddling legs, stiff limbs, twitching, drooling, urination/defecation :contentReference[oaicite:6]{index=6}.
• Focal (partial): Localized twitching, unusual vocalization, chewing or staring, while the cat stays conscious :contentReference[oaicite:7]{index=7}.

• Post-ictal Phase:

Disorientation, blindness, pacing, lethargy or excessive sleepiness may persist minutes to hours after :contentReference[oaicite:8]{index=8}.

3. Common Causes of Cat Seizures

a. Brain-derived (intracranial):

• Tumors (meningioma, lymphoma), encephalitis, hydrocephalus, head trauma, brain parasites (e.g., Toxoplasma) :contentReference[oaicite:9]{index=9}.

b. Outside brain (extracranial):

• Liver or kidney disease, hypoglycemia, hypert hyroidism :contentReference[oaicite:10]{index=10}.
• Toxin exposure—e.g., permethrin-based flea treatments used on cats :contentReference[oaicite:11]{index=11}.

c. Idiopathic epilepsy:

No structural cause found—rare, usually in cats aged 1–6 years :contentReference[oaicite:12]{index=12}.

4. Immediate First Aid 🆘

1. Keep calm, keep other pets and kids away
2. Time the seizure—if > 2–5 min or clustered, it's an emergency (status epilepticus) :contentReference[oaicite:13]{index=13}
3. Move cat only if in danger, using a towel to avoid bites/scratches
4. Do NOT put anything in their mouth
5. Afterwards, make a quiet space; contact your vet promptly

5. When to Call the Vet or ER

• First-ever seizure
• Seizure longer than 2–5 minutes or repeated within hours
• Difficulty breathing after seizure or abnormal recovery
• Clusters of seizures or unwitnessed events
• Signs of toxin ingestion or metabolic disease

6. Diagnostic Process

• Full physical and neuro exam
• Bloodwork, urinalysis, liver/kidney panels, blood sugar
• Screen for toxins (e.g., permethrin)
• Imaging (MRI/CT) and cerebrospinal fluid analysis—if brain disease suspected

7. Treatment Options 💊

a. Address underlying causes:

• Manage metabolic diseases, remove toxins, treat infections
• Surgery or radiation for tumors, antibiotics/anti-inflammatories for encephalitis

b. Anticonvulsant medications:

• **Phenobarbital:** first-line; requires blood monitoring; 2–3 mg/kg q12 h, reduces seizures by ~93% :contentReference[oaicite:14]{index=14}.
• **Levetiracetam (Keppra):** fewer side effects, 2–3× daily dosing :contentReference[oaicite:15]{index=15}.
• **Zonisamide:** once or twice daily, effective and well tolerated :contentReference[oaicite:16]{index=16}.
• **Gabapentin:** adjunct anticonvulsant, pain-relief; useful in cats :contentReference[oaicite:17]{index=17}.
• **Imepitoin/Pexion:** newer anticonvulsant, limited data in cats :contentReference[oaicite:18]{index=18}.
• **Avoid diazepam orally and potassium bromide** due to risk of liver damage and lung disease :contentReference[oaicite:19]{index=19}.

Anticonvulsant therapy is often lifelong; abrupt discontinuation can be dangerous :contentReference[oaicite:20]{index=20}.

8. Emergency Medication at Home

Rectal diazepam (1–2 mg/kg) can be used short-term during prolonged seizures—follow with immediate vet care :contentReference[oaicite:21]{index=21}.

9. Monitoring & Adjustments

• Keep a seizure log: date, time, duration, type
• Regular vet visits with blood tests—especially with phenobarbital
• Adjust doses or add medications for breakthrough seizures

10. Prognosis & Quality of Life

• Varies with cause—manageable with medications (> 70% cats tilt fewer fits)
• Symptomatic causes (tumors, kidney disease) may carry guarded prognosis
• Idiopathic cases may live long, comfortable lives with consistent medication :contentReference[oaicite:22]{index=22}.

11. Prevention & Supportive Care

• Avoid toxin exposure—especially flea products for dogs :contentReference[oaicite:23]{index=23}.
• Control diseases through vaccination and check-ups
• Manage stress and anxiety—gabapentin or pheromones
• Maintain safe environments: no high drop hazards if a seizure hits
