Whether It Is Safe

Wheatgrass is safe for cats, and there’s no reason to worry about your kitty consuming it. However, make sure your cat is eating wheatgrass in moderation. And, of course, consult a vet if you are unsure if your four-legged friend should eat wheatgrass or if you notice something strange with the feline after it consumes the grass.


Wheatgrass has a high percentage of chlorophyll, a natural blood purifier. Plus, wheatgrass helps slow down aging and is suitable for older cats. Additionally, wheatgrass is a highly concentrated liquid. Some people believe it can help suppress appetite in overweight cats, making the felines lose weight healthily.

On the same note, wheatgrass promotes digestion and can help reduce the occurrence of hairballs in your Kitty. The high magnesium levels in wheatgrass produce enzymes that are also helpful for pregnant cats. Again, wheatgrass promotes the growth of healthy bacteria in the digestive system while killing unwanted bacteria. The result is a shiny, healthy coat for your furry friend.

Among other things, cats with dental issues will likely benefit from consuming wheatgrass. It’s just that this type of grass can treat and prevent dental decay. The same goes for elderly kitties or cats with eye problems, as wheatgrass has a high vitamin content to help remedy this condition. In addition, wheatgrass binds onto heavy metals in the gut and eliminates them from your kitty’s body.

Cats with mobility issues and those with arthritis can also benefit from wheat grass. Wheatgrass helps regenerate muscle and bone tissue with high mineral content.

Side Effects

Wheatgrass has side effects, most of which revolve around the digestive system. For example, your feline friend might vomit or defecate a lot after consuming wheatgrass. It’s just that if your kitty cannot digest wheatgrass, the undigested material obstructs the gut. That can result in secondary problems, including dehydration and a loss of appetite.

Besides, wheatgrass cultivated outdoors might contain herbicides, which can harm your kitty. So, to be safe, plant wheatgrass yourself indoors or in your yard.

 Additionally, consult a vet if your cat exhibits the above symptoms after eating wheatgrass.
