Can cats eat raw yeast dough?
No — raw yeast dough rises in the stomach and the yeast produces alcohol. Both together are a dangerous combination for cats.
Which substance is dangerous?
Raw yeast dough is doubly dangerous: in the warm stomach it keeps rising, stretching the stomach painfully and in the worst case dangerously — and the fermenting yeast produces ethanol, which enters the bloodstream and causes alcohol poisoning. Baked yeast pastry no longer carries these dangers but is still unsuitable (salt, sugar, raisins in some pastries).
How much is dangerous?
Even a stolen lump of dough is a problem — the dough continues working in the stomach, and cats are extremely sensitive to alcohol. The amounts in a piece of rising dough are enough.
Symptoms of poisoning
A bloated, painful belly, retching, restlessness — plus the alcohol signs: staggering, drowsiness, slowed breathing, hypothermia.
Emergency: what to do?
Raw dough eaten? Contact the vet immediately — stomach distension and alcohol production develop while you wait. Do not induce vomiting; the sticky dough can block the airway.

Frequently asked questions
Why does yeast dough produce alcohol?
The yeast ferments sugars into carbon dioxide and ethanol. In the warm stomach this continues — the cat is poisoned from within.
Is baked yeast pastry dangerous too?
No longer via yeast or alcohol, but bread and pastry are needless for cats and may carry raisins, salt or sugar — keep it away anyway.
My cat licked at rising dough — how bad is it?
Depends on the amount. Watch the belly and behaviour and call the vet in doubt — dough keeps rising in the stomach.
Which baked goods are safe for cats?
None, really. Bread and pastry are unnecessary carbohydrates; anything with raisins, chocolate or xylitol is dangerous on top.
