Why Do Dogs and Cats Eat Grass Sometimes?

Claire Smith, Vet

Dogs and cats may eat grass in order to make themselves vomit if they feel unwell. Cats are exclusive carnivores and have no requirement for fruit or vegetables, but some do have a taste for grass.

We believe that this may help with the movement of food and hairballs through the gastrointestinal tract. Eating grass may also provide cats with extra fibre and trace elements.

Indoor cats without access to grass may start chewing other potted plants so we recommend buying a pack of ‘cat grass’ to grow so that they do not eat potentially poisonous house plants.

Some dogs will make a daily routine of eating grass, unlike cats, their digestive tract and metabolism can digest fruit and vegetables. 

Most experts believe that we don’t need to worry if our dogs and cats eat small amounts of grass. However, if your pets start eating more grass than usual, vomiting frequently, or you notice any other symptoms then please contact us for further advice.
