Why Do Cats Eat Grass? Understanding This Natural Feline Behavior

Have you ever caught your cat nibbling on grass, only to wonder what could possibly be appealing about this seemingly unappetizing snack? As cat owners, we often observe behaviors that leave us puzzled, and grass eating ranks among the most common. At Oklahoma Veterinary Specialists, we understand your concern for your cat's wellbeing, which is why we've created this comprehensive guide to explain this natural feline behavior.

Is It Normal for Cats to Eat Grass?

Yes, grass consumption is entirely normal for cats. In fact, research from the University of California, Davis found that 71% of cats were observed eating plants at least six times throughout their lifetime. While indoor cats may have limited access to grass, many still seek it out when available. This behavior has deep evolutionary roots and serves several important functions for your feline companion.

Why Cats Are Drawn to Grass

Natural Digestive Aid

Cats are obligate carnivores with digestive systems designed primarily for processing meat. However, grass serves as a natural digestive aid in several ways:

• Hairball Management: When cats groom themselves, they inevitably ingest hair that can form uncomfortable hairballs. Grass contains fiber that helps move hairballs and other indigestible materials through the digestive tract. Learn more about hairball prevention at our Internal Medicine Services page.
• Natural Emetic: Sometimes cats eat grass specifically to induce vomiting when they feel unwell or have consumed something disagreeable. The grass blades tickle the throat and stomach lining, helping your cat purge whatever might be causing discomfort.

Nutritional Benefits

While cats receive most of their nutritional needs from meat, grass provides certain nutrients that complement their diet:

• Folic Acid: Grass contains folic acid (vitamin B9), an essential vitamin that supports oxygen transport in the bloodstream and assists with cell growth.
• Fiber Source: The fiber in grass aids in overall digestive health and can help regulate bowel movements.

When to Be Concerned

While grass eating is generally harmless, certain circumstances warrant attention:

• Excessive Consumption: If your cat suddenly begins consuming unusually large amounts of grass, it could indicate an underlying digestive issue that requires examination by a veterinarian.
• Vomiting After Eating Grass: Occasional vomiting after grass consumption is normal, but frequent or persistent vomiting could signal a problem. Contact our emergency team if your cat is experiencing uncontrollable vomiting.
• Access to Treated Grass: Ensure your cat only has access to untreated grass. Lawns treated with pesticides, herbicides, or fertilizers can be toxic to cats.
• Houseplant Confusion: Some cats may not distinguish between grass and houseplants, some of which can be toxic. The ASPCA provides a comprehensive list of plants toxic to cats that every cat owner should review.

Safe Ways to Satisfy Your Cat's Grass Cravings

If your cat enjoys grass but you're concerned about safety or access, consider these alternatives:

• Cat Grass Kits: Pet stores and online retailers offer cat grass growing kits, typically containing wheat, oat, barley, or rye grass, which are safe and easy to grow indoors.
• Monitored Outdoor Access: If possible, allow supervised outdoor time in untreated areas where your cat can safely graze on grass.
• Regular Veterinary Check-ups: Maintain regular wellness visits with your primary veterinarian to ensure your cat's dietary behaviors remain healthy. Should any complex issues arise, our board-certified specialists are available for more advanced care.

When Professional Care Is Needed

If grass eating is accompanied by concerning symptoms such as lethargy, weight loss, decreased appetite, diarrhea, or increased vomiting unrelated to grass consumption, it's time to seek veterinary attention. These could indicate underlying conditions requiring professional diagnosis and treatment.

At Oklahoma Veterinary Specialists, our board-certified internal medicine specialists are equipped with advanced diagnostic tools to identify and address complex digestive issues. Working collaboratively with your primary care veterinarian, we ensure your cat receives comprehensive care tailored to their unique needs.
