5 effective tips for a thriving cat grass garden

Cat grass has many benefits for cats, from helping soothe an upset stomach to helping prevent boredom in your indoor kitty. When you grow your own cat grass, you’ll be able to give your cat a safe source of grass to munch on. Growing cat grass is relatively easy — it grows quickly, so you’ll be able to see the results of your efforts in just a few days. Even if you’ve never done any gardening previously, you can successfully start your own garden of cat grasses with the right tips and preparation. These tips can help make your cat grass gardening experience a success.

Start with the right supplies

At the most basic, you’ll need:

  • Cat grass seed
  • Potting soil
  • A pot

You can buy these supplies separately and even use what you already have at home. Cat grass seeds are most commonly wheatgrass, oat, barley, or ryegrass seeds. You can buy these seeds at your local garden center or find plenty of retailers that sell them online.

If you want to go the organic route, then be sure to buy not only organic seeds but also organic potting soil.

Rather than buying your supplies separately, you might consider buying a cat grass growing kit. Many of these kits include all the supplies you need to get going.

Find the right spot

If you plan to grow the grass indoors, you’ll have more control over how much water it receives, and you can keep it protected from inquisitive cats who might want to munch on it before it’s ready. You’ll need to find a spot where the pot will get plenty of sunlight. Alternatively, you might grow the grass outdoors on a porch.

Give your grass the right start

To get your grass seed started, fill a pot with potting soil and then sow the seeds into the soil. Push the seeds about ¼-inch deep into the soil. Then, keep the soil moist to prompt the seeds to sprout.

Put the pot in a sunny place to help keep the grass growing. You’ll need to water the soil periodically, but definitely don’t overwater since you can kill off the grass. Use your finger to test the soil — if it’s dry and grainy, then it’s time to water.

Make watering easier

Using a small watering can give you more control as you water and can prevent you from accidentally spilling too much water into the pot. Alternatively, you can use a small spray bottle.

While your grass is still short, you can cover the pot with a layer of plastic wrap. This can help keep water from evaporating, so you don’t have to water it as often. Make sure that the plastic wrap is layered over the pot lightly since putting it on too tightly will restrict air circulation and can lead to mold.

Care for your grass once it’s grown

Cat grass grows quickly, so you should have plenty of grass ready within about a week. Before letting your cat munch on the grass, make sure it’s free of bugs and pests.

Your cat may naturally mow down the grass, which actually encourages it to continue growing. If your cat leaves behind uneven patches, you can give the grass a quick trim with scissors to keep it all growing evenly.

The grass will need plenty of sun to stay alive, so park it in the sunniest window or move it to your sunporch or another sunny spot. Even with plenty of care, the grass will probably eventually die, so as your cat starts grazing on one pot, consider planting another pot to have plenty more grass ready.

Growing a cat grass garden takes a little time, but it can pay off with a happier, healthier cat. Cat grass may help support your cat’s digestive system, and eating grass also keeps indoor-only cats entertained. When you grow your own cat grass, you know just how it’s been cared for and exactly what you’re giving your cat. This helps eliminate the potential for your cat to ingest grass that’s been treated with pesticides, like he might come across when outside. With a few pots of cat grass at different growth stages, you can keep even your enthusiastic eater well supplied with tasty grass that’s ready for snacking at any time.

Few first-time cat owners expect their cats to be affectionate, yet many cats seek their owner's attention. Compared to dogs, cats are typically thought of as more standoffish and less loving. That's certainly not always the case. You may be surprised when your otherwise aloof cat prefers to sleep in your bed over any other place in the house, but cats have many reasons for wanting to sleep in your bed. Read on to learn why your cat likes sleeping in your bed and the pros and cons of letting them do so.

Reasons your cat likes sleeping on your bed
How did your bed become your kitty's favorite sleep space? Several reasons could be in play.
Your cat loves you
Though they sometimes act indifferent, cats love people just as much as dogs do. Sleeping in your bed may be your cat's way of letting you know they care. When your cat sleeps with you, they show that they enjoy your company. This is especially common if you met your cat during the first four to nine weeks of their life when imprinting occurs. If you were a stable and caring presence during this time, you've likely imprinted on your cat and gained their complete adoration and trust.
Your bed is oh-so-comfortable
Cats can sleep up to 15 hours a day -- they are sleep pros. They’ve probably tried to nap in every spot in your home, so they know the comfiest, warmest, and best locations for napping. It makes sense that they would try sleeping in your bed. And all the blankets and pillows you put on your bed for yourself only make it more enticing for your cat. After all, you find your bed comfy, so why wouldn’t they?
