No, cats should not eat oysters.
Oysters can be potentially dangerous and should not be included in a cat’s diet. Raw or undercooked oysters may contain harmful bacteria or parasites. These can cause food poisoning or digestive problems in cats. Oysters can also be harmful to a cat’s health due to the high sodium content.
It is always best to stick to a balanced cat food as the most suitable variant to maintain the health of cats. Consult with your veterinarian if you have any concerns about your cat’s diet or if you would like to provide special treats.
