Are Sardines Good for Cats?

Yes, sardines are good for cats. Sardines are a type of small, oily fish that offer many benefits to both humans and animals. 

Let’s look at some of the benefits sardines can offer our feline friends.

Benefits of Feeding Sardines to Cats

  • Sardines are a good source of protein. Sardines are an excellent source of protein for cats. Protein helps support muscle growth and repair, which is vital for all animals, including cats.
  • Sardines are a good source of omega-3 fatty acids. Omega-3 fatty acids are essential for maintaining healthy skin and coat. They can also help reduce inflammation in the body.
  • Sardines are a good source of vitamins B12 and D. Vitamin B12 is vital for maintaining a healthy nervous system, and vitamin D is essential for bone health.
  • Sardines contain minerals like calcium, iron, and copper. All of these minerals are important for cats. For example, calcium helps support bone health, iron helps maintain a healthy immune system, and copper helps absorb iron.
  • The omega-3s (DHA and EPA) in sardines have been shown to help prevent or fight off various cancers and malignant tumors in cats. 

In addition, the anti-inflammatory properties of these fatty acids are associated with mood improvement. This may provide some relief for cats who suffer from anxiety or depression.

  • Sardines are a great way to keep your cat hydrated if they’re not drinking much water.

What are the Risks of Feeding Sardines to Cats?

While there are many benefits to feeding sardines to cats, there are also some risks to consider. 

The Danger of Mercury Poisoning

The biggest risk is that sardines can be high in mercury. Mercury is a toxic metal that can build up in the bodies of animals (and humans) that eat fish that contain high levels. 

One study discovered that cats fed tuna had mercury and selenium in greater levels within their tissues. 

Symptoms of mercury poisoning, according to another study carried out, included:

  • Loss of balance
  • Convulsions
  • Tremor
  • Mood change
  • Impaired optical reflexes 
  • Muscle weakness
  • Poor muscle control leading to clumsy movement

If you think your cat has mercury poisoning, take them to the vet immediately.

Possibility of Choking on the Bones

Sardines contain small bones that cats could choke on. For this reason, removing the bones from the sardines before feeding them to your cat is essential.

Risk of Oil Contamination

Some canned sardines are packed in oil, which can harm cats. To avoid this, always check the canned sardine’s label to ensure they’re packed in water rather than oil.

High Salt Content

The high salt content in sardines can be dangerous to cats, especially if they eat them regularly. An excessive intake of salt can lead to dehydration and electrolyte imbalance.

Tips for Safely Feeding your Cat Sardines

  • Remove the bones from the sardines before feeding them to your cat.
  • Check the canned sardines label to ensure they’re packed in water rather than oil.
  • Feed sardines to your cat in moderation.

How to Make Sardines for Cats

  • Open the can of sardines and wash off any oils or brine. Canned sardines that are high in sodium should be avoided.
  • Remove the bones from the sardines. You can do this by gently pressing down on the fish with your fingers and pulling out the bone.
  • Once all of the bones have been removed, cut the sardines into small pieces and feed your cat the sardines in moderation as part of a healthy diet.
