Do Cats Fart? What Causes Gas in Cats and When to Worry
Yes, cats fart — though far less noticeably than dogs or humans. Feline flatulence is normal but can sometimes indicate a digestive issue.
Why Cats Fart Less Than Dogs
Cats are obligate carnivores with a shorter, simpler digestive tract than dogs. They also eat more slowly and swallow less air. Their diets are typically lower in fermentable carbohydrates — the main fuel for gas-producing gut bacteria.
Normal Causes of Cat Gas
- Eating too quickly and swallowing air
- Dietary change — switching foods disrupts gut bacteria temporarily
- Dairy products — most cats are lactose intolerant
- High-fibre foods
- Certain vegetables in treats
When Cat Gas Is a Problem
- Frequent, loud, or smelly gas
- Gas combined with bloating, diarrhoea, or vomiting
- Weight loss alongside digestive symptoms
- Gas after dietary changes that persists more than a week
Conditions That Cause Excessive Gas
- Inflammatory bowel disease (IBD)
- Food intolerance or allergy
- Intestinal parasites
- Hairballs affecting gut motility
What to Do
If your cat's gas is occasional and they are otherwise healthy, no action is needed. Persistent, foul-smelling gas with other digestive symptoms warrants a vet check.
