Can cat eat vegetables and raw seafood?

Since kitties are our best friends, we want to treat them just like us. We want to care for them, play with them, and keep them healthy. Sometimes, we miss understanding whether it is safe for furry friends when we feed them with similar food. We eat different kinds of vegetables ranging from tasty carrots, green beans, and fried onion along with delicacies like seafood. Many of us wonder can cat eat vegetables and raw seafood.

Since a cat’s digestive system is not as complex as ours, there are certain limitations in what we feed and how we feed them. Cat’s internal system is made for digesting meat and there is no replacement for that. However, we can feed vegetables and seafood in the right way in small amounts as a treat to furry beings. Let’s look at various vegetables and seafood types that a cat can eat and cannot eat below:

Vegetables that cats can eat

Vegetables are an important source of vitamins, minerals, fiber, and water. However, there are few vegetables such as onion, garlic, and others that a cat should avoid.

Sweet Potatoes

Also, please avoid feeding raw carrots since they can choke your cat.


Lettuce is low in calories and contains more water. It is a good treat for cats and it helps in balancing hydration. It also has high fiber and helps in the cat’s digestion. Since kitties usually like to chew plants, offering lettuce for its chew time is one of the best options.


Cauliflower helps cats having arthritis. It is a good treat that has antioxidants, anti-cancer properties. Offer this to your kitty in moderation as a boiled treat. Also, remove leaves and stem before feeding them to your cat. If you give this in large amounts, it can cause extreme diarrhea so be cautious of the amount.

Small amounts of asparagus are good. It has fiber content and helps in the cat’s digestion. Since it is alkaline in nature, adding too much to a cat’s feeding habits can cause bladder stone formation and be detrimental to the cat’s health.

Green Beans

This is a healthy diet for human beings as well as their furry partners. It has lots of fiber in it and if cats are overweight, it is a good food to feed them. It also has oxalates in them and so it must be used in moderation again. If it is canned beans, please check out sodium levels and ensure low sodium levels are fed to kitties.
