Cat grass can be a great way to keep your cat happy and entertained.

But how long does cat grass last? Many factors go into how long the grass will last, including how often you feed it and how much sunlight it gets.

In this blog post, we’ll tell you everything there is to know about storing cat grass and how long cat grass lasts.

What is Cat Grass?

Cat Grass has also been called catnip, and it is a plant that contains Nepetalactone.

Cats are attracted to the smell and will chew on it.

It can be grown from seed or purchased in a plant form at the store.

Cat Grass is typically fed to cats as a treat, not for food purposes (although some people feed their cat Cat Grass).

You should never provide your cat grass that has been chemically treated with fertilizers and pesticides.

To grow it yourself, you need to soak the seeds in water overnight before planting them one inch deep into potting soil or garden dirt.

You can purchase it at any store but make sure that the package says “for animal use only” because many plants have chemicals sprayed on them that are poisonous to animals.

Be careful when purchasing from big box stores since they often sell non-organic versions of Cat Grass and other plants without specifying that they’re organic.

How to Store Cat Grass?

The best place for storing pet food like cat grass is inside of an airtight container or sealable zipper-style freezer bags, so as long as you don’t lose them, they’ll stay fresh until the next time you need them.

Store it away from heat or sunlight to preserve the oils.

You can also store dried catnip in a sealed container in the refrigerator to extend its freshness and place it in the freezer until needed for use.

If you’re looking for a quick and easy way to freshen up your cat’s diet, Cat Grass is just the thing.

The bright green foliage will entice your cat to nibble, and the seeds offer a nice crunch for those who enjoy chewing on items like straws or cotton balls.

The question is: how long does Cat Grass last when it’s been cut?

Cat Grass can last anywhere from two to three weeks when adequately cared for.

The best way to care for Cat Grass is by misting it with water every day and trimming the leaves as needed.

A fresh cut will usually stay fresh and green before becoming paler or yellow over a few days, which means you’ll want to replace your Cat Grass more frequently than those who don’t need their grass trimmed often.

How to Tell if Cat Grass is Bad?

Here are some signs that your cat grass may be bad.

If you notice any of these symptoms, it is essential to dispose of the plant and replace it with fresh roots as soon as possible.

The first thing to look out for is wilting leaves.

If your feline’s food plant starts to look like it is dying, that means the roots are not absorbing enough water or nutrients from the soil and need replacing.

Color changes may also indicate a problem with cat grass – brown leaves suggest nutrient deficiency, while yellowing indicates over-fertilization.

Another sign that your cat grass may be bad is when the plant has a slimy or wet top layer.

The effect of this slime will depend on what caused it, but in general, it’s best to replace the roots with fresh ones if they are covered in slime for an extended period.

You may be able to tell if cat grass is bad if leaves get blisters or other visible skin irritations.

Throw out the plant immediately and contact someone for advice on treatments.


In conclusion, cat grass is a wonderful alternative to traditional cat food.

It provides vitamins and minerals that are not in regular cat food, promotes healthier digestion, decreases the likelihood of cats developing diabetes or other blood sugar-related problems.

Furthermore, you can grow the plants yourself with only minimal effort.

Cat Grass stays fresh for a month after being cut and can last even longer if stored in an airtight bag or container in your fridge.

So give it a try today.
