Raw dough

Raw dough

Raw yeast dough is toxic to cats in two distinct ways. The live yeast ferments sugars in the warm stomach environment, producing carbon dioxide gas and ethanol. The CO2 causes painful abdominal bloating and can distend the stomach to dangerous levels, while the absorbed ethanol causes rapid alcohol poisoning.

Important Notes

Toxic mechanism 1: yeast fermentation produces CO2 — abdominal bloating, distension, and risk of gastric dilation

Toxic mechanism 2: ethanol production from fermentation — rapidly absorbed; cats lack alcohol dehydrogenase, causing CNS and respiratory depression

Symptoms: distended abdomen, vomiting, lethargy, disorientation, weakness; ethanol intoxication causes unsteady gait, low body temperature, slow breathing

Baked bread is safe — the heat kills yeast and evaporates alcohol; only raw dough poses this risk

Contact your vet immediately if your cat ingests raw yeast dough

Possible Symptoms Reported in Cats

Gastric Distension (Bloating) and Abdominal Pain

Gastrointestinal · Early (often within the first few hours).

Respiratory Distress and Depression

Respiratory · Progressive (within 1 hour to a few hours).

Metabolic Acidosis and Hypoglycemia

Hematological · Progressive (usually within an hour and worsening over time).

Severe CNS Depression (Seizures and Coma)

Neurological · Progressive (as fermentation continues and ethanol levels peak).

Neurological Impairment (Ataxia and Disorientation)
