Why Cats Eat Grass

One day, a pet owner saw the sweetest thing while outside in their garden. One of their dogs picked up a mouthful of grass and brought it to another dog, who had an upset stomach. It actually put the grass into the sick dog’s mouth! It’s as though animals have evolved to know when and how to heal themselves. If wheatgrass shots are good for humans, it stands to reason that grass may be beneficial to our pets as well.

However, cats are a little different. They are obligate carnivores. This term means that they have to eat a meat-only diet. So why do cats eat grass if they only eat proteins derived from meat?

The Benefits of Cats Eating Grass

Grass of any variety contains high levels of folic acid and fiber. Folic acid is an essential vitamin that cats need for development and strength. These enzymes increase the amount of hemoglobin in the blood, which leads to higher oxygen levels. If your cat eats grass in excessive amounts, it could indicate that its diet is lacking in folic acid.

If your cat has a well-balanced diet with adequate amounts of iron-rich proteins, the reason it’s eating grass may be because of the fiber content. Grass has natural laxative properties and is the pet equivalent to a bowl of all-bran cereal. Your cat will head for the grass to get that ball of fur in its stomach moving towards the other exit.

Interestingly, you can tell what your cat is getting from grass for by checking out what type of grass it favors eating. If it prefers the broad stalked varieties of grass (the kind found in most garden lawns), it is searching for fiber and its laxative effect. If your cat makes a beeline for spikier grasses (like those found on the curb), this means your cat needs nutrients to help heal an upset stomach.

What Happens After My Cat Has Eaten Grass?

If your cat needed the grass for an upset stomach, you might find that it vomits soon after eating the grass. This is purposeful so whatever was making them feel queasy can be purged. Cats digestive systems don’t contain the necessary enzymes that enable them to activate vomiting on their own. Eating a large amount of spikey grass stems helps to help them naturally regurgitate.

You may see upon closer inspection of your cat’s vomit, that it contains mouse meat, feathers, parasites, and even tails or teeth. These items caused irritation to your cat’s bowel and activated its instinct to eat grass. When a cat has eaten an irritant, it is always better to expel the substance than keeping it in. If all that detritus stayed inside its digestive tract, it could lead to problems.

If you have no control over what gets sprinkled on the lawns around your home, you should invest in a wheatgrass growing kit for your cat. This is the perfect solution to ensuring your cat only eats grass untainted with fertilizers and pesticides.
