Cat Grass

Does your cat make it his mission to turn every houseplant into his personal snack shack? Why do cats eat green leaves, or if he’s an outdoorsy guy, grass?

There’s no clear-cut answer to this question. Rather, there are a few theories.

Theory #1: Enzymes

Grass tends to induce vomiting because cats are missing the digestive enzymes required to metabolize plant matter. It’s believed this process helps rid the digestive tract of other items the cat is having a hard time processing.

Theory #2: Laxative

Whether it’s their own fur from grooming or fur leftover from a hunting expedition, cats have a hard time passing hair all the way through their intestinal tracts. Some owners assert cats munch on grass to help move things along.

Theory #3: Evolution

A veterinarian at the University of California-Davis suggests the habit of eating grass comes from centuries of big cats incorporating vegetation into their diets to counteract intestinal parasites. Of course, modern family cats are fed specialized recipes to avoid such health issues, but grass-eating is probably a remnant behavior.

Proper Planting

Regardless of the why your cat likes to eat grass, the fact remains that he seeks it out. Why not give the pet his own cat-friendly plants, such as cat grass.

Cat grass is typically a combination of oat, rye, barley and wheat grasses, and is easy to grow if you follow these basic gardening steps:

  1. Container selection

Most likely your kitty is going to want to honker down among the blades. It’s just what felines do. Choose a container large enough for your cat to snuggle in, but one that’s also shallow so it’s not super easy to knock over .

  1. Start from seeds

If you start with seeds, you don’t have to worry if the seedlings will survive transplanting. Place the container on a saucer or tray to catch any water that slips through, add a layer of dirt and sprinkle the seeds. Cover the seeds with another light layer of soil. Tip: Spritz the dirt with water before spreading the seeds, so it’s pre-moistened.

  1. Cover for germination

Loosely cover the mini garden with plastic wrap and store at room temperature. Tip: Avoid placing the container in direct sunlight at first because the heat can become too intense. Water when the soil feels dry to the touch.

  1. Encourage sprouting

You should see evidence of sprouts relatively soon. Once you do, remove the plastic and reposition the container to a sunnier spot. When the seedlings reach 3-4 inches, they are cat-ready.

To keep you kitty happy, plant pots in intervals.
