The Science Behind Why Cats Love Grass đŸŒ±

Why your cat craves a chew—and how to give them the safe, healthy fix they deserve

It might look odd—your cat, eyes wide, crunching on grass like a tiny lawnmower. But this behavior isn’t just random or cute. It’s instinctive, biologically backed, and surprisingly beneficial.

In this post, we dig into the science behind why cats eat grass, what they gain from it, and why ZestiGreens Cat Grass Kits are the safest, healthiest way to support this natural habit—right from your kitchen counter.


1. Grass Helps Cats Clean Their System

Grass contains natural fiber and mild irritants that help your cat do one very important thing: self-clean. Chewing grass can trigger vomiting, which helps eliminate fur, feathers, and other indigestible bits that cats naturally consume. It’s like an internal reset button.

Bonus: Not all cats vomit after eating grass. For many, it helps move things along gently instead.

2. It's Packed with Micronutrients

Grass offers more than roughage. It’s a source of folic acid, chlorophyll, and trace minerals that aid in oxygen transport, cell repair, and digestion. Wild cats often ate the stomach contents of herbivorous prey—domestic cats mimic this instinct by turning to grass.

3. It's an Evolutionary Holdover

Even though cats are obligate carnivores, research shows that grass-eating behavior is hardwired into feline biology. Studies suggest it served as a way for wild cats to purge parasites and maintain gut health. Your indoor cat? Same instinct, cleaner environment.

4. Indoor Cats Need Safe Options

Most outdoor grass is contaminated with pesticides, herbicides, or car exhaust—not ideal for your fur baby. That's why ZestiGreens Cat Grass Kits are a game-changer. Our kits grow indoors, pesticide-free, and ready in just 5–7 days. No mess, no mystery.

5. A Bored Cat Is a Chewing Cat

Cats chew for entertainment, curiosity, and sensory play. Giving them their own grass to nibble reduces the risk of them turning your houseplants into a salad bar (and many of those plants are toxic to cats).

Solution? Grow their greens with ZestiGreens, and protect your pothos in the process.

Yes. Our organic blends are safe, non-toxic, and vet-recommended. Just introduce it gradually and monitor for any unusual behavior (rare but good practice).
