Why Do Dogs and Cats Eat Grass?

Why Do Dogs and Cats Eat Grass?

Sep 04, 2024

It’s not uncommon to see your dog or cat munching on grass, and it might make you wonder why. While it’s long been assumed that they do this to induce vomiting, the real reason is a bit more complex—and has less to do with making themselves sick than you might think.

Do Dogs and Cats Eat Grass to Make Themselves Vomit?

The idea that pets eat grass to trigger vomiting has been a popular belief for a long time. However, research from the University of California, Davis, shows that only about 25% of pets vomit after eating grass. So, if vomiting isn’t the main reason, what are they actually seeking?

It turns out, dogs and cats eat grass because they’re in search of something important: nutrients, specifically fibre. While they may sometimes be low in the B vitamin folic acid, grass-eating is primarily about balancing their digestive systems by consuming fibre.

Why Fibre Is Essential for Dogs and Cats

Fibre plays a key role in your pet’s digestive health. It helps firm up stools in cases of diarrhoea and nourishes the good bacteria in their gut. This balance is crucial because when the bad bacteria in their gut grow unchecked, it can lead to digestive issues like vomiting, diarrhoea, and unpleasant odours.

That’s why it’s important to ensure your dog or cat is getting enough fibre in their diet. For example, highly advanced green banana flour is a great source of prebiotic fibre, which can help keep your pet’s digestive system in check. 

In short, when your dog or cat is snacking on grass, it’s usually their way of telling you they need more fibre to maintain a healthy, balanced digestive system.
