TL;DR: A cat having a seizure with uncontrolled bowel movements is a high-priority medical emergency requiring immediate veterinary evaluation. Documenting the episode with a video helps your vet distinguish between seizures and other conditions for faster, more accurate treatment.

What happens when my cat has a seizure with uncontrolled bowel movements?

  • Abnormal electrical activity in the brain causes the cat to lose conscious control over their body.
  • Episodes often include involuntary muscle contractions and the relaxation of sphincters.
  • Uncontrolled bowel movements or urination, known as autonomic involvement, are common symptoms of a generalized seizure.

Is it an emergency if my cat has a seizure and loses bowel control?

  • Loss of bowel control during a fit indicates a significant neurological event and is considered a high-priority medical emergency.
  • Immediate veterinary evaluation is necessary even if the cat appears to recover quickly.
  • Recurrent seizures or a single episode lasting more than three minutes can lead to permanent brain damage or life-threatening hyperthermia.

How does documenting my cat's seizure help the veterinarian?

  • Capturing a short video or a photo of the aftermath (including stool) provides critical diagnostic information.
  • Photos help the clinical team identify secondary issues like gastrointestinal distress or evidence of toxins.
  • Videos allow veterinarians to distinguish true seizures from other conditions like fainting (syncope) or heart issues, ensuring faster treatment.

Clinical Context (Merck Veterinary Manual)

Regarding seizures and loss of bowel control in cats, a detailed neurologic examination should be completed. A thorough physical examination should be performed, including abdominal palpation to identify abnormalities. Rectal examination is required to provide a fecal sample.
