Why Do Cats Eat Grass When Sick

Cats eat grass when they are feeling sick for a variety of reasons. One such behavior that many cat owners have observed is their tendency to eat grass, especially when sick. However, they also need certain nutrients and vitamins found in plants. 

Cats cannot digest plants as efficiently as herbivores like cows or rabbits. It is where grass comes in – it contains folic acid, which is a B-complex vitamin that cats need for their overall health. 

When cats feel unwell, they may instinctively seek out grass to get the nutrients they need to aid their recovery. Moreover, cats’ digestive system is sensitive, and they can be prone to constipation and hairball blockages. 

Eating grass can help them induce vomiting, relieving any indigestion or blockages in their stomach. It’s a natural way for cats to purge their system and feel better. 

As a cat owner, it is important to monitor your cat’s behavior and ensure that they have access to safe and healthy grass if they choose to eat it.
