Frequent vomiting, soft stools, gas, and appetite fluctuations are signs of a sensitive stomach -- and it is one of the most common complaints cat owners bring to the vet. While occasional hairball vomiting is normal, regular digestive upset signals that something in the diet (or the cat) needs to change.
Common Causes of Sensitive Stomach
- Food intolerance: Reaction to specific ingredients (not immune-mediated)
- Eating too fast: Gulping food causes regurgitation
- Low-quality food: Fillers, artificial ingredients, poor protein sources
- Sudden diet changes: Switching food without gradual transition
- Inflammatory Bowel Disease (IBD): Chronic GI inflammation requiring vet diagnosis
- Hairballs: Especially in longhaired breeds
- Food allergies: Immune reaction to specific proteins

- Pumpkin: 1 tsp plain canned pumpkin adds gentle fiber

Frequently Asked Questions
Is occasional vomiting normal for cats?
Occasional hairball vomiting (once or twice a month in longhaired cats) can be normal. Vomiting food or bile more than once a week is NOT normal and warrants veterinary investigation. The myth that "cats just vomit" has allowed many treatable conditions (IBD, food allergies, pancreatitis) to go undiagnosed for years.
