Why Do Cats Eat Grass?

If you have a cat who is allowed access to the outdoors, I’m sure that at some point you’ve probably seen her nibbling on a few blades of grass in your yard. I’m also sure that immediately afterward you’ve probably seen her throw that grass right back up. It might seem odd that kitty would enjoy eating something that obviously makes her sick, but there are a few theories that seem to indicate grass nibbling actually serves a valuable function. why does my cat eat grass

It Must Be Something I Ate

Cats may eat grass as a way of ridding their digestive tract of something unpleasant or inedible. Grass nibbling may be of particular importance to outdoor cats who eat prey in order to get rid of any inedible parts that get swallowed (feathers, bones, etc.). It can also be a way for a cat to get rid of some hair that gets swallowed during grooming which may cut down on hairballs.

Speaking of Hairballs

Hairballs that don’t get vomited back up, go through the intestinal tract. Sometimes those hairballs don’t pass so easily out the other end. Cats might instinctively know that the added fiber from eating grass may help lubricate things in the south end so hairballs and fecal matter pass more easily.

Providing Nutrients

Another theory is that cats may eat grass for the nutrients it contains. Typically, when a cat eats prey such as a mouse, she would also be consuming the contents of the prey’s stomach. The prey’s tummy typically contains grasses and grainswhy does my cat eat grass.

Is Eating Grass Harmful?

Eating grass is typically not harmful. If you have an outdoor cat though, you wouldn’t want her eating grass that has been chemically treated. The safest way to provide grass for your cat is to grow a pot of it for her. You can either purchase a “kitty greens” kit at your local pet product store or grow your own using rye, wheat or oat seeds. In fact, providing your cat with some safe kitty greens may help prevent her from nibbling on dangerous houseplants – which ARE toxic to cats.

Don’t confuse grass-eating with plant-eating. All houseplants are toxic to cats and most are poisonous. Keep plants out of your cat’s reach.
