Can cats eat raw yeast dough?
No. Raw yeast dough is dangerous for cats in two ways: it can keep expanding in the stomach and cause a blockage, and the yeast makes alcohol, which is toxic to cats. Keep rising dough out of reach and call your vet if your cat eats any.

Why
Raw dough contains some alcohol and produces carbon dioxide. Once swallowed, the yeast keeps working in the stomach: the dough expands and can cause an obstruction, while the alcohol it produces is absorbed into the blood. Cats are especially sensitive to alcohol.
Signs to watch for
- Swollen, bloated tummy
- Trying to vomit without bringing anything up
- Wobbly walking or seeming confused
- Unusual weakness or sleepiness
What to do
Contact your vet or a pet poison helpline right away. Note how much dough your cat ate and when. Don't wait for signs to appear, and don't try to make your cat sick at home.

Why is raw dough dangerous if it's not a poison itself?
Raw dough contains live yeast. In the stomach it keeps rising and producing alcohol, so it can both cause a blockage and lead to alcohol poisoning.
