Cat grass is a total must-have for indoor kitties. To keep your furry friends happy and healthy, that grass needs to be fresh and well-maintained. Finding mold on your cat grass is definitely a bummer—and a health hazard. Let’s dive into why this happens and how you can prevent it.
Are you overwatering your greens?
In the wild, cat grass ancestors often grew in marshy areas. This means the plants are totally fine with moist soil, but there’s a big difference between “moist” and “drowning.” Constant standing water is the enemy here. If you’re overwatering, you’re basically inviting mold to move in.
Instead of one big weekly soak, try watering more frequently with smaller amounts. Another pro-tip: use a well-draining potting mix or add a layer of pebbles at the bottom of the pot to prevent water from pooling. You can also try “bottom watering” by placing the pot in a saucer filled with water. This lets the roots drink what they need without the top of the soil getting soggy and moldy.
Keep these tips in mind for healthy grass:
- Water the soil mindfully—don’t just dump it in.
- Check regularly to make sure the soil isn’t waterlogged.
- High humidity in the air actually helps the grass stay healthy and strong.
Is moldy cat grass safe for my cat?
Short answer: No. Even if you only see a tiny bit of mold on a few blades, consider it a red flag. You should never let your cat snack on moldy plants. While you could technically try to harvest seeds from the plant to start over, it’s usually not worth the risk of cross-contamination.
The good news is that cat grass seeds are super affordable and easy to find online or at your local pet store. Plus, growing your own cat grass is a breeze! You can plant it year-round indoors in a simple pot or a shallow dish.
Cat grass is so important for our feline friends. When they munch on it, it triggers a natural gag reflex that helps them cough up hairballs. Without it, those fur clumps can cause some serious digestive issues. Keeping a fresh, mold-free supply is one of the best things you can do for your cat’s health. And remember, there are several different types of grasses you can try to see which one your kitty prefers!
