It’s a common belief that cats are fond of eating fish or fish-based food. However, there are some shocking facts to this theory. As a part of the marine family, eels also fall under the category of fishes. Here we will highlight some hidden facts about cats and their love for fish-based cat food. Keep reading to know more about whether cats can eat eels and how to serve eels to your feline friends.

Eels are ray-finned marine creatures belonging to the fish family, and just like others of their type, these snake-like fishes have a tiny sharp bone running down their spine. They make clean and healthy eating for many animals and humans. However, cats require a protein-based diet, and eels can not fulfill their nutritional requirements. Therefore, giving eel as a sole meat option for cats is not recommended.

Is Eel Good For Cats?

Cats are generally picky eaters. They might like the taste of some food items which aren’t necessarily good for their health. It’s a slightly similar situation when it comes to eels. 

Eels and other fishes are highly dangerous for felines in raw form. However, there are safer ways of consuming them. Taking a look at an eel’s nutritional chart shows us that these sea creatures are enriched with omega-3 and fatty acids, which are great for cats. Fish oils also help regulate heart muscles and lower the risk of atrial fibrillation. Hence, making eels a healthy meal for cats suffering from obesity. 

Besides being omega-healthy, eels also contain calcium, potassium, zinc, iron, magnesium, and other minerals. These together help nourish the cat’s body by keeping its bones and muscles strong. However, check with a vet before trying to feed this meat to your cat.

Is Eel Bad For Cats?

You must be wondering why eels would be unfit for cats to consume even after all the goodness it has. Well, just like milk, most cats are allergic to eels as well. This allergen might be due to the protein histamine in them. Due to this allergic reaction, some cats suffer from long-term depression and a loss of appetite. 

They might undergo symptoms of diarrhea and other stomach issues. The greatest threat that eels bring to cats is because of the enzyme thiaminase. According to researchers, this enzyme alters thiamine in a cat’s body, lowering the overall vitamin B in their blood. 

To sum up, an excess of eel-based food can be bad for cats. However, it can be enjoyed as a snack once in a while. 

Is Eel Dangerous For Cats?

Researchers tell us that even a few drops of eel blood are enough to kill a living creature. There’s a poison found in eels that is highly dangerous for cats and humans alike. As soon as it is ingested, muscles cramp, including the heart, leading to sudden and painful death. 

Luckily this poison is dissolved if the eel is cooked thoroughly. This is also the reason why an eel is never served raw.  

Besides the poisoning, the raw eel will also destroy thiamine in cats. Hence, if we talk about raw eels, they are also highly dangerous for cats and other felines. Fortunately, there are some safer ways to feed this treat to your cats. 

What Happens If A Cat Eats Eel?

Talking about cats and eels, there is one thing worth mentioning here. Most cats love eating eels to the extent that they even go on hunger strikes if served with anything other than an eel or eel-based cat food. So after having a few eel-based food items, cats will become addicted to it. This habit becomes unhealthy after some time because cats need Vitamin K to stay fit, and eels do not have sufficient vitamin K to fulfill cats’ requirements. However, as a responsible cat owner, you should only feed eel to your cat as a snack or once a week. 

Can Cats Eat Raw Eel?

Raw eel contains poison in the blood, as discussed above. This poison causes many health issues and instant death in high amounts. Eels need to be cooked thoroughly. There are various ways to kill this poison and make eel edible for cats. You can grill, bake, boil or just stir fry the eel to make it harmless and healthy to be consumed by cats. Apart from that, raw fish is like a breeding ground for various bacteria, which will cause food poisoning in cats.

Can Cats Eat Cooked Eel?

The rule to serve eel to your cat is simple. Either boil it, bake it or grill it. Cooking the eel kills any harmful bacteria on it and even eradicates the poison. What needs attention here is that cats aren’t fond of heavy spices. They like the taste of raw fish as it is. 

Hence while cooking the eel, you don’t need to add flavorings. After the eel is well cooked, carefully remove the central bone from the eel. This step is extremely crucial. The sharp bone in eels can cause choking hazards in kittens. Shred the meat into tiny pieces to make it easy for cats to eat.

Can Cats Eat Eel Sushi?

You might wonder if cats can also enjoy some eel sushi because they love eels. Well, you’re right. Cats can eat sushi too. However, various points must be considered before adding them to their meal. 

First and foremost, start by serving tiny amounts of eel before jumping to sushi. This step will help you detect if your cat is allergic to eel. Although sushi has protein, it does not fulfill your cat’s daily nutrition. The sticky rice in sushi is not something cats need to eat often, as rice is rich in carbohydrates. 

In simpler words, it is safe for cats to eat eel-based sushi but not as a daily meal. It can be consumed once in a while as a snack to enjoy. If you’re making sushi at home just for your pet, avoid adding flavorings as cats like the authentic taste more.
