Tracking CBD effects on seizures in cats is a systematic process that helps the vet understand if therapy should continue. 📊🐱 Here's how to do it simply and effectively.

  1. Keep a "seizure diary" 📓
    What to record daily

  • Date and time of seizure ⏰ (note exact start time and duration).

  • Description: what happened (twitching, falling, drooling, "blackout," involuntary urination/defecation).

  • Frequency: how many attacks per day/week (clusters = 3+ in 24 hours — emergency).

  • Triggers: what happened before (food, stress, sleep, loud noises).

Example entry
02/02/2026, 14:37 — seizure lasting 1:45 min. Cat suddenly fell on side, left leg twitching, drooling, 30 sec "blackout." Before: ate at 14:00, sleeping since 13:00. CBD given at 13:30 (1 mg).

  1. Track cat's overall condition 📈
    Create a simple table (notebook or Google Sheets) by weeks:

Week Number of seizures Average duration Appetite/sleep Side effects (drowsiness, stool) Notes
1 (pre-CBD) 7 per week 2 min Normal — Baseline: phenobarbital 3 mg/kg
2 (CBD 0.5 mg/kg) 5 per week 1:30 min Normal Mild drowsiness —
3 (CBD 1 mg/kg) 3 per week 1:15 min Good — Improvement

  1. Success indicators of CBD effect 🎯
    Positive changes (what vet considers "result"):

  • Reduction in total seizure count (e.g., from 7 to 3–4 per week).

  • Shorter seizure duration (from 2+ min to <1.5 min).

  • Fewer cluster seizures or multiple-seizure days.

  • Cat's overall condition improves (more active, better appetite).

No effect (may need adjustment):

  • Seizure count/duration unchanged or worsening.

  • New triggers or clusters appear.

  1. Record side effects and interactions ⚠️
    Red flags (contact vet immediately):

  • Loss of appetite, food refusal >24h 🍽️

  • Vomiting, diarrhea, unstable stool 💩

  • Pronounced drowsiness, "slowness," coordination issues 🐌

  • Behavior changes (excessive aggression or apathy).

Lab monitoring (vet will prescribe):

  • Liver enzymes (ALT, AST) every 2–4 weeks.

  • Blood levels of anti-seizure meds (CBD affects their metabolism).

  1. When/how to report to vet 📞

  • Weekly: send diary summary (seizure count, condition changes).

  • Before visit: print/screen table + monthly seizure calendar.

  • Emergency: clusters, worsening, side effects — call immediately.

Example vet report
Hi, thanks for the protocol. After 2 weeks on CBD 1 mg/kg + phenobarbital:

  • Seizures: 8 → 4 per week

  • Duration: avg 1:20 min (was 2:10)

  • Appetite/activity: normal

  • Bloodwork (01/25): ALT 120 (normal <100), no other changes

  1. Additional tracking tools 📱

  • Apps: Seizure Tracker, EpiDiary, Pet First Aid (seizure calendar functions).

  • Video: record short clips of seizures (5–10 sec) — shows vet typical pattern.

  • Weight/temp: track weekly for overall condition.

Weekly checklist ✅

  • Recorded all seizures (time, duration, description).

  • Weighed cat, checked appetite/activity.

  • Gave CBD exactly per schedule (time, dose).

  • Noted side effects.

  • Prepared vet report.

Key point: systematic records are your "works/doesn't work" proof. Without them, vet can't adjust protocol, and you risk missing important changes. Stay in touch with your vet! 💙📞
