10/17/2023 - 2 Comments

Cats and tuna share a special bond. For many cat owners, this fish is a common staple of their pet's diet. But can cats eat tuna?  This article will answer that question and explore the possible health implications and risks of feeding your cat tuna.  Let's dive into it to get the best guides!

Can Cats Eat Tuna? Is Tuna Good For Cats? 

Can cats have tuna? The answer is Yes! Cats can consume tuna in moderation as an occasional treat. Many pet owners choose tuna as the most popular food for their cats. These animals love the strong taste and smell of tuna.  However, consider several things when feeding your feline friends this food. You should only provide this seafood as an occasional treat. Your pets may love the fish's taste, but it shouldn't be a primary part of their diet.  That's because this fish doesn't contain all the vital nutrients felines require for their health. Furthermore, overfeeding your pets can cause health issues and nutritional imbalances.   Besides, if you want to feed your pets this seafood, opt for tuna canned in water instead of oil. The second option contains high-fat content, so it will lead to digestive problems for felines.  Giving your cats plain tuna without seasonings and additives is also a good idea, as these ingredients are toxic to felines.  Remember that this fish contains a high mercury level. This substance is harmful to your pets if over consumed over time.  You should consult your vet if you are unsure whether this seafood is safe for your cats. These experts will provide advice and guidelines based on each cat's health condition and dietary needs. 

Health Benefits

Tuna is a nutritious addition to your cat's diet for many good reasons when fed in moderation!

#1. Maintain a Healthy Weight

Tuna is an excellent source of lean protein that can help your felines maintain a healthy weight. Unlike other meats high in fat, this fish is low in calories and can help your cat feel fuller for extended periods.  Furthermore, giving your furry friends this seafood can also help prevent obesity.

#2. Improve Your Cat's Appetite

If your cat is a picky eater, feeding them tuna can help improve their appetite. Tuna has a strong aroma and flavor that can entice even the most finicky of cats. Also, this fish can help stimulate their appetite and encourage them to eat.

#3. Fight Inflammation

Inflammation can cause many health issues. Meanwhile, tuna has plenty of omega-3 fatty acids. Providing your felines with this seafood can help reduce inflammation and promote overall health.

#4. Boost Immune System

Tuna also has vitamins and minerals. These substances can help boost your cat's immune system.  Vitamin D in this fish can help with calcium absorption, while vitamin B12 can help maintain healthy nerves and blood cells.  Additionally, this food is a good selenium source. It can help protect your cat's cells from damage.

Potential Risks

Is tuna bad for cats? While tuna brings several benefits for your pets, it may cause some drawbacks. 

#1. Risk of Mercury Poisoning

One of the most significant risks associated with feeding this seafood to furry friends is the potential for mercury poisoning.  Tuna is famous for containing high levels of mercury. It can build up in your cat's body and cause severe health issues.  Symptoms of mercury poisoning in cats include loss of coordination and muscle weakness. Limiting tuna intake or avoiding it altogether is best.

#2. Nutritional Imbalance

Another risk of feeding cats this seafood is that it can lead to a nutritional imbalance in their diet. Tuna is high in protein but lacks many essential vitamins and minerals that your furry friends need to stay healthy.  Feeding your pets much fish can result in deficiencies in nutrients like calcium and vitamin E. Sticking to cat food specifically formulated for their dietary requirements is best to ensure your pet's diet meets all its nutritional needs.

#3. Tuna/Fish Allergies 

Cats, just like humans, can also have allergies. Tuna and other fish are common allergens in cats. So overfeeding them can cause an allergic reaction.  Your pets may experience symptoms like difficulty breathing or vomiting. Without immediate treatment, it can be lethal.  It's essential to monitor your felines after feeding them this fish and to watch out for any signs of an allergic reaction.

#4. Steatitis

Giving your cat too much tuna can also lead to steatitis, a condition caused by an excessive intake of unsaturated fatty acids. This health issue can cause pancreas inflammation. And your cats may experience a lack of appetite and lethargy. 

Potential Risks

Do Cats Like Tuna? 

The answer is yes. Most cats do like tuna. Besides omega-3 fatty acids, tuna also has protein.

Tuna lacks essential nutrients that your furry friends need, such as taurine. Ensure your pets receive all the needed nutrients. You should feed them balanced homemade or commercial cat food.

Cats can eat both canned and fresh tuna. However, not all types of tuna are safe for cats.
