Can Cats Eat Prawns and Shrimp?

Prawns and their smaller cousins shrimp are a popular seafood, and in warmer climates are a common addition to Christmas day celebrations. They can be consumed hot and cold.

These crustaceans are high in protein, low in calories and are a good source of omega 3 fatty acids. They also contain zinc, iodine, sodium, calcium, phosphorous, potassium, magnesium, iron and vitamins B and E.

Can cats eat shrimp and prawns?

Yes, the occasional treat of shrimp and prawns are perfectly safe for your cat as long as they don’t contain other ingredients such as chilli or garlic (which is toxic to cats).

Not all cats can have shrimp or prawns, and should not be fed to cats under the following circumstances:

  • Cats who are on a food elimination trial to evaluate for food allergies cannot have any other types of food apart from their prescription hypoallergenic diet or the trial will be invalid.
  • Cats who are on a low-iodine diet such as Hills y/d to manage hyperthyroidism. The thyroid gland uses iodine in food to produce thyroid hormones. Cats with hyperthyroidism have elevated thyroid hormones due to a benign hormone-secreting tumour on the thyroid gland. Hyperthyroidism can be managed with a prescription diet that is low in iodine. Therefore we do not recommend other foods which contain iodine to cats on this diet.
  • Cats with known allergies to seafood or prawns and shrimp.
  • Speak to your veterinarian if your cat is on any other type of prescription diet to treat a medical condition.

How to feed shrimp and prawns to a cat

Prawns and shrimp are healthy (and delicious), but they are not a complete and balanced diet for cats and therefore should be a treat only. Treats must not make up more than 10% of your cat’s diet.

They can be fed cooked or raw, you can leave the shell and tail on or remove (and de-vein). Some cats love the crunch of prawn shells.

Do not feed prawns that are coated in a sauce or contain other ingredients such as garlic or butter.

Do not feed prawns that have expired.

Remove uneaten prawns after 20 minutes.


If your cat develops symptoms such as vomiting, diarrhea or itchy skin after eating prawns discontinue and speak to your veterinarian.

In rare cases, anaphylaxis can occur, which is a life-threatening, severe allergic reaction. Symptoms include itching, swelling, difficulty breathing, and collapse. If your cat displays any of these symptoms, immediate veterinary attention is essential.
