Why Do Cats Eat Grass?

Before diving into the question of "what grass do cats eat," it's helpful to know why cats are drawn to greenery in the first place. While cats are obligate carnivores, many occasionally nibble on grass for a variety of reasons. For indoor cats, grass provides texture and fibre that can help with digestion and reduce hairball formation. Outdoor cats may use grass as a natural aid to ease minor stomach upsets. For health and safety, it’s essential to offer non-toxic, cat-friendly varieties.

When most people search "what grass do cats eat," they’re actually seeking Dactylis glomerata. This perennial grass is easy to grow, lush, and highly palatable to cats. It thrives in New Zealand gardens and in pots indoors, allowing pet owners to offer fresh, safe greens year-round. Unlike some random lawn grasses, Dactylis glomerata doesn’t contain harmful chemicals or sharp blades, making it gentle on sensitive mouths and digestive systems.

Growing Cat Grass is simple. Sow seeds in trays or small pots, keep them in a sunny position, and water regularly. Within a week or two, you’ll have a mini-meadow ready for your furry friend. Rotate pots for a constant supply, ensuring your cat never has to roam outside for a snack.

Is Lawn Grass Safe for Cats?

Not all lawn grasses are suitable. Lawns treated with pesticides, herbicides, or fertilisers should never be nibbled by cats. Dactylis glomerata, grown at home or in pots, ensures your cat stays safe from chemicals and toxic varieties.
