Can Ferrets Eat Tuna? (Benefits/Risks)

Yes, ferrets can eat tuna.

However, your pet ferret may find tuna’s smell strange or too strong, so he may not eat it, but it is edible and safe to eat for ferrets so don’t worry about that.

Tuna contains a large amount of protein and fats, which ferrets need to maintain their health.

Ferrets are obligate carnivores so they need animal-based proteins with high biological values for optimal nutrition. Ferrets are also very active animals so they have high caloric needs as well. Tuna contains both animal-based proteins and essential fats that your ferret needs.

Tuna typically contains a good amount of phosphorus and magnesium which is beneficial to the nervous system and bones, but too much can be hazardous. The ratio of calcium to phosphorus in tuna is about 50:1, meaning it has a high calcium content. Ferrets have a very high demand for calcium because they utilize it so quickly when growing.

Ferrets are lactose intolerant, so keep this in mind when trying to get your ferret to eat tuna. Ferrets cannot digest milk or milk products like cheese because they lack the enzyme (lactase) that is needed to break down milk sugar (lactose). Consuming too much dairy can cause soft stool and diarrhea.

Tuna also contains L-tryptophan, which is an essential amino acid that ferrets need for healthy skin and coat. Tuna can also help to calm and relax your pet because it has melatonin and other nutrients (such as magnesium) that may help rid stress and insomnia.

Is tuna good for ferrets to eat?

Tuna is very high in important nutrients for ferrets.

Tuna contains selenium, calcium, phosphorus, magnesium, and potassium which are all needed in a ferret’s diet. Tuna also has iron, niacin (B3), thiamine (B1), riboflavin (B2), vitamin A, and vitamin D which ferrets need, but in smaller amounts than what they get from tuna.

Tuna also has high amounts of EPA and DHA, omega-3 fatty acids that are needed for a healthy heart and optimal organ function. It naturally contains the amino acid taurine, niacin (B3), vitamins A and D, and is a good source of calcium needed for strong bones.

Is it bad for ferrets to eat tuna?

The only thing that really makes tuna bad for Ferrets would be the high calcium content, which can cause health problems if too much is consumed.

Ferrets need fat in their diet but not an overabundance of it because they are very prone to obesity. Too much protein can also be harmful to ferrets because it increases the amount of calcium that is excreted in their urine.

Ferrets are lactose-intolerant, so milk and dairy products should not be fed to them in large amounts because they can cause soft stools and diarrhea.

Too much tuna also contains high amounts of phosphorus which ferrets cannot metabolize as other animals can. An excess amount of phosphorus can lead to bladder stones and crystals, which block the urinary system.


In conclusion, ferrets can eat tuna. Tuna has so many nutrients that your ferret needs to stay healthy and happy. However, the same amount of tuna eaten by a human would probably kill or seriously harm a ferret because their bodies cannot tolerate too much protein at once.
