How Long Does Cat Grass Really Last?

Cat grass is a quick, healthy treat that keeps indoor cats happy and entertained. But if you’ve ever grown a fresh pot and watched it wither in days, you’re not alone. Let’s break down what the packaging says, what really happens at home, and how to get the most out of your kitty’s greens.

The Claims vs. The Reality

Most pots of cat grass are sold with the promise of lasting 2–3 weeks. In perfect conditions - bright light, careful watering, and maybe a little luck - that’s possible.

In real homes, especially indoors, cat grass often lasts closer to 7–14 days before it starts to yellow or wilt. Think of it more like fresh produce than a permanent plant. It’s meant to be enjoyed while it’s young, tender, and green.

One Cat vs. Multiple Cats

• One cat: Usually nibbles slowly, so the pot often wilts before it’s fully eaten. Expect around two weeks.
• Two cats: More grazing means the pot may be gone in about a week.
• Three or four cats: The grass is often chewed to the roots in just a few days.

The bottom line? The more cats, the faster the pot disappears.

Tips to Keep It Fresh Longer

• Place it in bright, indirect sunlight.
• Water sparingly, but don’t let it dry out.
• Trim tall blades to keep them from flopping over.
• Start new pots every couple of weeks so you always have fresh grass on rotation.

Why Whisker Field Farms Cat Grass Lasts Longer

We know flimsy little pots don’t cut it. That’s why Whisker Field Farms cat grass comes in bigger, heavier containers that won’t tip over during play. Our clear pots make it easy to see when the soil is drying out, and the deeper soil base gives roots more room and helps keep the grass greener for longer.

We also only source only fresh, USA grown organic seeds for our cat grass for better germination and healthier plants, so your cat won't be disappointed when their grass doesn't grow!

Remember, Cat Grass is a fresh crop that needs replacing, but with our kit design, you’ll enjoy healthier, longer-lasting grass, and happier cats.
