How To Grow Cat Grass From Seed

Growing cat grass is basically the same as growing anything from seed.  Most of the kits that can be bought online come packaged with everything you will need, including the soil or growing medium, the seeds, and the container. The growing medium often contains vermiculite, which is very light in weight. All you need to do is follow the instructions given.

How to grow cat grass from seed. Use these directions if you have seeds but no instructions.

1. Choose a container with drainage.  

2.Place a saucer underneath the container to protect surfaces.

3. Fill with a good-quality potting mix. We always have a compost pile going, so adding a small amount of compost is something I almost always do when doing any planting. It does not matter if you do not have compost.

4.Dampen the mix but do not saturate. Sprinkle some seeds across the surface. Cover with a light sprinkling of soil. Give a light water.  Using a spray bottle will help to avoid over watering the seeds.

5.Keep the soil moist and within days you should see the shoots appear.

6. Once the shoots are a reasonable height, kitty will be knocking you over to get to the grass.

Cat Grass Buying Guide and FAQ

Why Do Cats Like Cat Grass?

Some people believe the cat will expel hairballs or vomit after eating cat grass which contains fiber. This may or may not be coincidence. That being said, if cat grass aids in digestion, that is a good thing.

Cats certainly love it. We all know that eating our greens is good for us in the form of vitamins, minerals and fiber so these are also positive benefits for the cat.

Note: Cat grass is not the same as lawn or what we commonly call grass.

There are some foods that cats definitely should not eat. Some are quite surprising.  It is worth finding out to prevent any problems from occurring in the first place.

Do All Cats Like Cat Grass?

Not all cats like cat grass but then cats do change their minds. Even if you had a cat grass refuser in the past it doesn’t mean that is forever.

A good idea is to have a couple of pots of cat grass on the go so that when one is more or less finished, you have the ‘one you prepared earlier’ and the cat will be impressed.

You can grow the seeds indoors or outdoors. It will depend on the climate where you live.  For the seeds to sprout, some warmth or a sunny spot is needed.  Just follow the procedure for growing seeds of any type in your area.

Do Dogs Like Pet Grass?

A regular doggie visitor to our house liked the cat grass just as much as the cat. 

We did not ever have to offer it to the dog or encourage him to eat it, he just seems to know it was okay for him to eat.

Neither the cat or the dog ate other household plants (well not while we were watching anyway) The cat didn’t ever eat too much. Just a few nibbles and he would be on his way.

If your cat has allergies this presents extra challenges. This article reviews cat food for cats that are hypoallergenic….And there is more here.

How Safe Is Cat Grass?

Cat grass is safe to give to your cat.  If you have grown it you know exactly what has gone into the preparation. However as with anything else, always observe your cat for any unusual symptoms after eating anything that varies from the usual diet, and this includes cat grass. Visit a vet if you have any doubts.

Where Can I Get A Cat Grass Kit?

Due to increased popularity, seeds, containers, and sprouting kits are readily available online and at pet stores.

Yep! I like it!

Problems With Growing Cat Grass

Mold can be an indication that the pot is too wet.

The pot may need to be moved to an area that has more ventilation or moved outside if the weather is warm. As with any gardening and growing, a certain amount of experimentation may need to happen if you don’t have success the first time. 

Don’t give up. Have another go.  It will make you happy and your cat happy, guaranteed!

Where Can I buy Cat Grass?

I initially bought our pet grass from a pet stall at a fair.  BTW, this is a really good little money earner for fetes/fairs as the grass can be planted out in containers several weeks before the date required, so that it is nice and healthy by the time the fair/fete comes around.  

If you have a pet it is impossible to not buy a pot of pet grass to take home for the cat.
