Can Cats Eat Cat Grass? 7 Facts About It

For cats, this is entirely typical behavior. Your cat is predisposed to this behavior.

Have no fear; feeding your cat cat grass is perfectly fine. Cat grass provides numerous advantages for your feline friend.

Indoor cats can get the same health benefits from cat grass as their outdoor counterparts by having it grown specifically for them.

Read on to find out how to grow cat grass indoors without risking the health of your cat.

What Is Cat Grass?

Cat grass refers to a group of grasses that are popular among feline snackers. The most nutritious kinds are usually cereal grain grasses like:

  • Oat
  • Wheat
  • Barley
  • Rye
  • Alfalfa

Catnip and cat grass are two entirely different things. Cats’ behavior can be altered by catnip, a plant in the mint family. Not even cat grass.

Benefits of Cat Grass

Although they are obligate carnivores, cats occasionally enjoy a salad of cat grasses. Your cat will love eating them, and you’ll both reap the health benefits they provide.

1. Hairball Removal

You know how horrible it is to see your long-haired cat (or short-haired cat prone to hairballs) try to cough up hair if you have one.

The high fiber content of cat grass aids in the digestion and elimination of hairballs.

2. Indigestion Relief

Cat grass is also useful for settling an upset stomach.

The natural instinct of cats to graze on grass in the wild may have evolved so that they can more easily vomit up the indigestible parts of the small animals they eat.

4. Mental Stimulation

Most cats really enjoy playing. The unique form and feel of the grass piques your cat’s interest and piques their natural hunting drive. If your cat is bored, try giving it some cat grass to chew on.

5. Prevents Parasites

Parasites in cats are another thing cat grass can help with. Parasites may be wrapped up in the grass and then either vomited out or released in the stool. This is one way that cats get rid of worms on their own.

6. Vitamins and Minerals

Last but not least, the vitamins and minerals that your cat needs can be found in abundance in cat grass. In particular, cat grass is rich in:

  • Three essential vitamins: A, B, and D
  • Sodium Folate
  • Chlorophyll

Chlorophyll has additional benefits, including reducing bad breath in cats.

Why Do Cats Like Cat Grass?

Cats have been observed nibbling on grass, including cat grass, for reasons that remain mysterious despite extensive study.

It was once thought that when a cat was sick, eating grass would help them feel better. Nonetheless, research1has called into question this assumption.

A survey of cat owners found that 65 percent of felines regularly consume plant matter.

The owners of only 6% of these animals reported feeling unwell prior to eating the plant, while 37% of those animals reported frequently throwing up afterward.

Since 94% of the cats in the survey appeared to be fine before eating anything, this would imply that cats don’t eat plants, including cat grass, to feel better.

. It has been hypothesized that eating cat grass can aid in the passing of hairballs. Would giving a long-haired cat, which is more likely to eat grass, help it cough up a hairball if it did make it sick?

Research conducted in Belgium2examined many species of wild canines and other canids as well as several species of wildcats such as lynx, cougars, pumas, and leopards.

This research confirmed that grass-eating was not limited to domestic cats, but was present even in wild felines.

Growing Cat Grass

It is best to feed your cat grasses grown in your own home if you intend to make grass a regular part of their diet.

Yard grass is vulnerable to contamination from harmful chemicals and pesticides. Also, if you grow grass indoors, your cat is less likely to ingest anything harmful.

Growing cat grass requires little effort. Grass can be easily grown at home with the help of a kit available at most pet stores.

The grass should be planted in the provided container. You should give it the recommended amount of water.

It will take about 10-14 days for the grass to mature enough for your cat to eat after the seeds have sprouted.

The grass should have reached a height of four inches by then. The grass can remain in the pot at all times. Instead, serve your cat from the dish itself.

Keep an eye out for mold between 1 and 3 weeks, but otherwise the grass should be fine. It’s time to replace the grass if it turns brown and wilted or if mold starts to grow on it.
