Can Cats Eat Acorns

Can cats eat acorns? Well, the short answer is a big NO. Acorns are pretty dangerous for your cat if ingested in an ample amount.

Mind you, and cats are curious by nature. And, though we may not think of acorns as something terrible, our adorable feline friends and acorns are a bad combination. 

Read on to know all about how feeding acorns to your cats may have an adverse effect on their health. So, let’s get started!

Can Cats Eat Acorn?

According to vet experts, as much as 75% of cats get poisoned after eating acorns. Not only does it cause poisoning, but it also increases the risk of intestinal blockage. 

Acorn poisoning has serious consequences because of a chemical present in it – called tannins. Tannins are produced from phenolic acids and are one of the main reasons for acorn poisoning. If left untreated, acorns can cause severe damage to the stomach and kidney. 

Also, keep in mind that tannin is a micronutrient that keeps herbivores away from a plant. And this chemical is abundant in acorns – especially before they ripen. But, over time, as acorns ripen, tannin levels decrease. 

Plus, there is also a special substance in acorns known as Gallotannin that can cause fatigue and discomfort alongside vomiting and diarrhea. 

Acorns with mold have to be some of the worst kinds of acorns to get poisoning from. Not only will they show symptoms of poisoning, but they will also cause fatal seizures. 

So, acorns are strictly prohibited for your beautiful furry friends.
