Tuna is highly sought after by many cats. Its intense aroma, soft texture, and high protein content make it a popular snack. But is tuna really healthy for cats? And what about canned tuna?

Why do cats love tuna so much?

Most cats are absolutely crazy about tuna – and that's no coincidence. The reason lies in the combination of:

• A strong fishy smell that appeals to their sensitive sense of smell.
• Umami taste, which cats particularly like (they hardly taste sweet, but umami tastes very distinct)
• A delicate consistency that is easy to chew and swallow – even for older cats or those with dental problems.
• Rapid positive reinforcement: Once eaten and loved – many cats demand it again and again.

But precisely this strong attraction makes it all the more important to pay attention to quality and quantity.

Is tuna good for cats?

Tuna can be healthy for cats. It should be fed as a supplement and be of good quality.

Tuna contains many important nutrients, including:

• High-quality protein for muscle building
• Omega-3 fatty acids for skin, coat and heart
• Important vitamins such as B12 and D
• Selenium and iodine for thyroid and immune system

However, feeding tuna should not become a daily habit. Cats need a balanced diet. They require all essential nutrients. Tuna alone is not enough. Too much tuna can cause problems.

Which tuna products are unsuitable for cats?

Not all canned tuna is suitable for cats. Many products in supermarkets are intended for humans, but they contain additives that can be harmful to cats.

1. Tuna in sunflower oil or vegetable oil

• Too fatty for a cat's sensitive metabolism
• Often leads to diarrhea or weight gain
• Plant oils do not provide any useful nutrients for cats.

Better: Tuna in its own juice – without oil.

2. Salted tuna

• Salt puts a strain on kidney function.
• Can lead to high blood pressure and dehydration
• Especially dangerous for older cats or cats with kidney disease

Look for "no salt" or "low sodium" labels when shopping.

3. Seasoned or marinated tuna

• Onion or garlic extracts are highly toxic to cats.
• Herbs, flavorings, and preservatives can trigger allergies and stomach problems.
• Products labeled "spicy", "hearty", or "Mediterranean" are also taboo.

Even small amounts can lead to health problems.

4. Raw tuna

• Contains thiaminase, an enzyme that breaks down vitamin B1.
• Can lead to nerve damage, muscle weakness, and cramps.
• Raw fish also carries the risk of bacteria or parasites.

Conclusion: Never feed raw tuna – unless it has been specially prepared for cats.

Tuna is delicious – but how do you feed it properly?

Tuna is a delicacy for many cats – but straight from the can isn't the best solution. Perhaps you've experienced this yourself:

• The cat gets diarrhea
• After that, he won't eat any more dry or wet food.
• Reacts with stomach upset or a dull coat

The reason? Many tuna products are intended for human consumption – containing salt, oil, or spices. This can lead to health problems in cats.

Heavy metals in tuna: An underestimated risk

Tuna are predatory fish. This means they can be contaminated with heavy metals like mercury. Regular feeding can lead to health problems.

• Kidney damage
• Nerve damage
• Long-term strain on the immune system
